Cable Accessories Technical Measures
Oct 11, 2017

1) the formation of the work of the low-voltage electric field electrode, when the local burr will also form a strong electric field strength of the situation, therefore, Cable Accessories but also trying to make the conductor surface as smooth as possible to achieve a smooth round without burrs.

2) to provide the capacitor current and fault current path, Cable Accessories so there is a certain cross-section requirements.

Semi-conductive shielding layer is used in the high-voltage cable to improve the surface of the metal electrode surface electric field distribution, Cable Accessories while improving the insulation surface of the electrical strength of the important technical measures.

1) first instead of the conductor to form a smooth rounded surface, greatly improving the surface of the electric field distribution,

2) At the same time, can be in close contact with the insulation, Cable Accessories to overcome the insulation and metal can not be close contact with the air gap weakness, Cable Accessories and the air gap shielding outside the workplace.

Insulation is a key structure that reliably isolates high voltage electrodes from ground electrodes.

1) to withstand the working voltage and a variety of over-voltage long-term role, so its electrical strength and long-term stability is to ensure that the entire cable to complete the transmission of the most important part of the task.

2) can withstand the thermal effect of the heat conductor to maintain the required electrical strength.

Advances in cable technology are largely determined by advances in insulation technology. Cable Accessories From production to operation, most of the test measurements are aimed at monitoring the various properties of insulation for the purpose.

The protective layer is an important guarantee for protecting the insulation and the normal and reliable operation of the entire cable.

Designed for a variety of environmental conditions with a corresponding protective layer structure. Mainly mechanical protection (longitudinal, radial external force), waterproof, fire, Cable Accessories anti-corrosion, anti-biological and so on. Various combinations can be made as needed.

Cable accessories are an integral part of cable lines, and cables are not working without accessories. Complete the transmission task is composed of cables and accessories of the cable line as a whole. It can be said that cable accessories are a continuation of the cable function. Cable Accessories The requirements of the cable body, such as conductor cross-section and surface characteristics, semiconducting layers, metal shields, insulation layers and sheaths, are also applicable to cable accessories, Cable Accessories especially intermediate fittings, Part should correspond to all parts of the cable. The terminal is basically the same, but the external insulation has a special.
