"Wire" and "electrical equipment with wire and cable" in the concept of no strict boundaries. Narrowly divided into "wire" and "cable", in a broad sense, collectively referred to as "cable". Generally speaking, it is considered as follows. 1) One called "wire", and other one called "cable".2) The small diameter is called "wire", and the large diam...

When selecting a cable, select the cable according to the usage, and don't want to be cheap. I think that the cable is cheap and can be guaranteed to meet the standards, and there are none in all. For example, overhead cables (xlpe insulated 2x16mm2 abc cable, PE insulated abc cable and aluminum service drop). Some suppliers offer low quality products to d...

Overhead cables are cables erected in the air. It is a commonly used cable with a very high market share in the power cable market.Overhead cables can transmit current or distribute current.Overhead cables can be divided into copper core cables and aluminum core cables according to the conductor material.The copper core cable is a cable with copper as the c...

Shielding layer has become necessary in medium-voltage and high-voltage cables, but there are still many incorrect and irregular technological processes in the manufacturing process of shielding layer. This leads to damage to the shielding layer.Consequences of shielding damageIf the shielding layer is unreasonably manufactured and processed, i...

Aerial Bunched Cables (Aerial Bundled Cable or simply ABC) are Overhead Power Lines. Usually, in this cable several insulated phase conductor are bundled together tightly with a bare neutral conductor.This thing makes a slight difference between normal uninsulated conductor, which have an air gap, and ABC. In Air Bunched Cable, type of overhead transm...

Generally, the bare wire core is exposed to the atmosphere and is easily corroded. Even the BV wire manufactured according to the requirements of GB5023--1985, commonly known as the "insulated wire", its pressure level is limited to low pressure, and the outdoor erection will be less than 5 years. Aging cracks and loses its original performance. The most o...

1, good insulation performanceDue to the extra insulation layer of the overhead insulated conductor, the superior insulation performance of the bare conductor can reduce the phase distance between the lines, reduce the insulation requirements of the support members of the line, and increase the number of circuits in the line on the same pole.2, good cor...

Insulation is to make the insulating material cover the outside of the conductor with different thickness according to the requirements of the withstand voltage. It plays the role of isolating the charged body from other parts. After the cable is energized, the conductor is heated. Therefore, the ideal insulating material should have good insulation pr...
