Components of an LV AB Cables Distribution Line

Low Voltage Aerial Bundled Cables, which have an insulating layer of XLPE, are an innovative concept for the distribution of electricity to households, street lights or other low voltage applications. These electrical distribution systems are practical not only in congested cities where the insulation provides safety and manoeuvrability but are also useful in rural areas where live line maintenance is much easier than using bare conductors. You can read more about this in our article on the “Advantages of Low Voltage Aerial Bundled Cables for Overhead Power Distribution”.

According to research published in 2017, “XLPE cables are expected to last or service well beyond the 40-year design life under normal circumstances”. However, this long lifespan can be severely reduced if improper clamps and connectors are used along with the AB Cable. According to the research, the most influential factor in ageing ABC cables is the use of non-standard cable connectors, accessories and clamps because they allow water ingress which slowly damages the cable.

The appropriate components to be used along with the AB Cable system are listed below.

1. Aerial Bundled Cable (ABC)

a. Insulated Messenger System: An insulated messenger system (also called the French system) consists of 3 black, weather-resistant XLPE or PE insulated phase conductors twisted along with an insulated messenger conductor made of a high strength Aluminum alloy which serves as a dual purpose earthing and/or neutral messenger wire.

b. Self-Supporting System (Two Core or Four Core System): The self-supporting cable system consists of 2 or 4 PE or XLPE black, weather-resistant insulated conductors. The mechanical strength of all the cables is equal such that, when strained, all the cables will equally bear the load of the system.

c. Uninsulated Messenger System: An uninsulated messenger system (also called the Finnish system) consists of 1-4 black, weather-resistant PE insulated phase conductors twisted around a messenger conductor made of a high strength Aluminum alloy.

2. Poles

a. Wooden Poles

b. Cement (RCC – Reinforced Cement Concrete, PCC – Plain Cement Concrete Poles)

c. Steel Tubular Pole (Stepped pole, Swaged pole).

d. Rail Pole.

3. Suspension System:

a. Suspension Clamps for LV AB Cables are used along with a bracket or other supporting hardware to suspend and grip, without damaging, the insulated or uninsulated messenger or the self-supporting system of a LV ABC system by means of an adjustable lock that accommodates a range of cable sizes.

4. Anchoring System:

a. Anchoring Clamps for LV AB Cables are used along with a bracket or other supporting hardware and are used to strain the insulated or uninsulated neutral messenger or the self-supported system to terminate into transformer leads or mains for industrial/residential supply. They are also used to provide angles to a LV ABC system without damaging the cable’s insulation.

5. Taking service lines or tap connections:

a. Service Clamps are used along with a bracket or other supporting hardware and is used to strain the insulated service conductor of an LV-ABC system without damaging the cable’s insulation. The main application of Service Clamps is to bring service connections to households or street lights.

b. Insulation Piercing Connectors are used on all AB cable systems (messenger wire as well as self-supporting system) to take tap connections. This tap can be used to continue the line, distribute the line, be used in street lighting or in-service connections to households.

6. Service line distribution

a. Distribution Boxes are used to take multiple connections from a single enclosure. These connections can be used for distribution to households.

7. Other Hardware

a. Midspan Joints are used for insulated ABC cables on stranded phase and neutral to join two cables.

b. Insulated BM Lugs are used for insulated ABC cables on stranded phase and neutral to terminate the cables.

c. Elastomeric or Heat Shrinkable End Caps are used to safely terminate the ends of the AB Cable. Elastomeric End Caps are usually supplied with insulation piercing connectors.

d. Fixing Nails are used to support Aerial bundled cable on façades.

e. Stainless Steel straps are used along with the Fixing Nails to accommodate an additional bundle if required. Stainless Steel Cable ties are also used to fix brackets and distribution boxes onto the electric pole.

f. Tensioner is used to tension the steel straps which are mounted on the poles to hold the brackets or distribution boxes in place.

Pump mechanical seal leakage cause

There are many types of mechanical seals for diesel trash pump, and the models are different, but there are five main leak points:  a, the seal between the sleeve and the shaft;  b, the seal between the moving ring and the sleeve;  c, Seal between moving and static rings;  d sealing between the stationary ring and the stationary ring seat;  e, Sealing between the sealed end cap and the pump body. In general, the leakage between the shafts of the bushings, the seal end caps and the engine driven water pump body is easier to find and solve, but it needs to be carefully observed, especially when the working medium is liquefied gas or high pressure, toxic and harmful gas, it is relatively difficult. some. The remaining leaks are difficult to distinguish and judge intuitively. It is necessary to observe, analyze, and judge the leak symptoms on the basis of long-term management and maintenance practices in order to draw correct conclusions.

 Dewatering pump

 I. Analysis and judgment of leakage causes  

1) Leak when installing the static test. After the mechanical seal is installed and debugged, it is generally necessary to perform a static test to observe the amount of leakage. If the leakage is small, there are problems with the moving ring or static ring seal; when the leakage is large, it indicates that there is a problem between the friction pairs of the moving and stationary rings. On the basis of preliminary observation of the leakage amount and judging the leakage location, the vehicle can be manually observed. If there is no obvious change in the leakage amount, the static and dynamic ring seals have problems; if there is a significant change in the leakage amount during the cranking, it can be determined that it is moving. There is a problem with the static ring friction pair; if the leakage medium is sprayed in the axial direction, there are many problems in the moving ring sealing ring, and the leakage medium is sprayed to the periphery or leaks from the water cooling hole, and the static ring sealing ring is mostly invalid. In addition, the leakage channel can also exist at the same time, but there are generally primary and secondary differences. As long as the observation is meticulous and familiar with the structure, it can be judged correctly.

 6 inch trash pump

2). Leakage that occurs during commissioning. After the static test of the mechanical seal of the pump, the centrifugal force generated by the high-speed rotation during operation will suppress the leakage of the medium. Therefore, the leakage of the mechanical seal during the test run is basically caused by the failure of the friction pairs of the moving and stationary rings after the failure of the seal between the shafts and the end caps. The main factors causing the failure of the friction pair seal are: 1, During operation, due to abnormal phenomena such as evacuation, cavitation, and rolling, a large axial force is caused to separate the moving and static ring contact surfaces; 2,  The amount of compression is too large when installing the mechanical seal, resulting in severe wear and abrasion of the end face of the friction pair; 3, The moving ring seal ring is too tight, and the spring cannot adjust the axial floating amount of the moving ring; 4, The static ring seal ring is too loose, when the moving ring is axially floating, the static ring is separated from the static ring seat; 5, There are granular materials in the working medium, and the friction pair is in operation during operation, and the end face of the moving and static ring seal is detected;6, The design selection is wrong, the sealing end face is lower than the pressure deviation or the sealing material is more cold-shrinkable. The above phenomenon often occurs during trial operation, and can sometimes be eliminated by appropriately adjusting the static ring seat, etc., but most of them need to be reassembled and replaced.  

3). Sudden leakage during normal operation. The sudden leakage of the centrifugal pump during operation is due to normal wear or has reached the service life, and most of them are caused by large changes in working conditions or improper operation and maintenance. evacuation, cavitation or rolling for a long time, resulting in seal damage; The actual output of the pump is too small, a large number of medium trailer mounted pump circulate, heat accumulates, causing gasification of the medium, resulting in seal failure; The return flow is too large, causing the sediment at the bottom of the suction side container (tower, kettle, tank, pool) to rise and damage the seal; For a longer period of time, there is no manual turning when restarting, and the friction pair tears the sealing surface due to adhesion; Increased corrosive, polymerizable, and gelatinous substances in the medium; The ambient temperature changes drastically; Frequent changes or adjustments in working conditions;  

Sudden power outage or downtime. The diesel engine irrigation pump suddenly leaks during normal operation. If it cannot be found in time, it will often cause a big accident or loss. It must be taken seriously and effective measures taken.  

 Secondly, several misunderstandings in the mechanical seal inspection of dewatering pump. The greater the amount of spring compression, the better the sealing effect. In fact, if the spring compression amount is too large, the friction pair may be sharply worn and burned instantaneously; excessive compression causes the spring to lose the ability to adjust the end face of the moving ring, resulting in seal failure. The tighter the seal diagram of the moving ring, the better. In fact, the dynamic ring seal is too tight and harmful. First, the wear between the seal ring and the bushing is intensified, and the leakage is premature. Secondly, the resistance of the axial adjustment and movement of the moving ring is increased. When the working condition changes frequently, the adjustment cannot be timely; thirdly, the spring is excessively fatigued and easily damaged; It is to deform the moving ring seal and affect the sealing effect. The tighter the seal ring of the static ring, the better. The static ring seal is basically at rest, and the relatively tight seal will be better, but too tight is also harmful. First, the static ring seal is caused by excessive deformation, which affects the sealing effect. Secondly, the static ring material is mostly graphite, which is generally brittle. Excessive force is easy to cause fragmentation. Third, it is difficult to install and disassemble, and it is easy to damage the static ring. The tighter the impeller lock is, the better. In mechanical seal leakage, leakage between the bushing and the shaft (interaxial leakage) is relatively common. It is generally believed that the leakage between the shafts is that the impeller locks are not locked. In fact, there are many factors causing leakage between the shafts, such as the failure of the inter-axis pads, the offset, the impurities between the shafts, and the larger shape of the shaft and the sleeve. The position error, the contact surface is broken, there is a gap between the components on the shaft, and the shaft thread is too long, which causes leakage between the shafts. Excessive locking of the lock nut will only lead to premature failure of the inter-axis pad. On the contrary, the lock nut is moderately locked, so that the inter-shaft pad always maintains a certain compression elasticity. During operation, the lock nut will automatically lock in time, so that the shaft is always in good condition. Sealed state. The new one is better than the old one. Relatively speaking, the effect of using a new mechanical seal is better than that of the old one, but the quality or material selection of the new mechanical seal is not appropriate. The large dimensional error will affect the sealing effect; in the polymerizable and permeable medium, the static ring is not excessive. Wear or not replace it as well. Because the static ring is in a static state for a long time in the static ring seat, the polymer and impurities are deposited as one body, which has a good sealing effect. The repair is better than not. In the event of a mechanical seal leak, it is rushed to be repaired. In fact, sometimes the seal is not damaged. It is only necessary to adjust the working condition or properly adjust the seal to eliminate the leak. In this way, it avoids waste and can verify its own fault judgment ability, and accumulates maintenance experience to improve the quality of maintenance.
