Cable Accessories The Elements Of
Aug 01, 2017

Cable accessories (English name: cable accessories) is the connection cable and transmission and distribution lines and related power distribution equipment products, generally refers to the cable cable connection and terminal connection, which together with the cable constitute the power transmission network, Cable Accessories cable accessories mainly based on The cable structure features not only to restore the cable's performance, but also to ensure that the length of the cable is extended and the terminal is connected. Cable Accessories The reliability of high-voltage cable accessories can be evaluated from electrical performance, sealed moisture-proof performance, mechanical properties and performance. Cable accessories affect the cable accessories are generally divided into terminal connections and connections, terminal connections are divided into indoor and outdoor terminals, Cable Accessories usually outdoor terminal refers to the outdoor cable connector, indoor terminal refers to the joint internal cable and electrical equipment; intermediate connection is divided into straight And insulation type two.

Cable accessories quality factor is diversified, Cable Accessories in principle there are several aspects:

  1, electrical performance. Electrical performance is good or bad quality first principle is to determine the cable accessories. The main consideration of the cable distribution of the electric field distribution is reasonable and appropriate measures to improve the electric field distribution, Cable Accessories the electric field strength, the dielectric loss and the product, such as insulation. At the same time, the stability of the performance must also be considered, including the chemical and physical properties of the cable accessory material and the stability of the structure. The stress control material properties are stable, for example, Cable Accessories the stress cone is easily deformed, the cable insulation shrinks the cable attachment and the electric field distribution measures to prevent The effects of various materials on the compatibility of the interface with stable performance, etc. In addition, should also consider the thermal performance of cable accessories such as dielectric loss, contact resistance of the conductor connection and its stability, thermal conductivity, thermal expansion and contraction affect the performance of electronic and mechanical components, and so on.

    2, sealing performance. Seal moisture resistance directly affects the electrical performance of the cable accessories and the life of the accessories. The terminal seal structure is reliable and stable. In general, Cable Accessories the middle connector should also have a matching metal moisture barrier, especially in direct or wet environments.

    3, mechanical properties. Cable Accessories The terminal should have enough bending, impact resistance. The middle joint should be able to withstand a certain tension and measures to prevent external damage.

    4, process performance. Process performance is an important cable accessories design and selection conditions, the installation process should be as simple as possible, Cable Accessories easy on-site construction, short duration, on-site environmental requirements and the technical level of workers is not high, Cable Accessories easy to control the quality of installation, reliable quality, and many more.

    5, the manufacturer's quality assurance system. Prefabricated cable accessories factory, factory provided rubber casting, prefabricated stress cone, Cable Accessories ceramic components such as housing, dipping agents, etc., are assembled in the field when assembled into the entire terminal or joint, Cable Accessories so the quality of each part manufacturing and installation process Directly related to the final product quality.
