Peroxide crosslinking

Peroxide crosslinking

The peroxide crosslinking method is a method of initiating crosslinking by adding a crosslinker. Its main advantage is that it is suitable for the production of cross-linked polyethylene insulated power cables of various voltage levels and various sections, especially medium and high voltage cables of 35kV and above.

Irradiated cross-linked cables

Irradiated cross-linked cables

In 1960, Rachem developed irradiated cross-linked cables. This method does not require the addition of a cross-linker. In the early fifties, the United States had discovered the use of radioactive isotopes, reactor waste, the reactor irradiation itself, and the energy of electron accelerators to crosslink polyethylene

Waterproof layer for high-voltage cables

Waterproof layer for high-voltage cables

Set to be used. However, for high-voltage cables, metal sheaths are generally specified. The use of extruded wrinkle aluminum metal sleeve is ideal, but a continuous aluminum press machine is expensive, with the development of welding technology, the reliability of wrinkle welding aluminum sleeve cable has become more and more recognized

The structure of cross-linked power cables and the cross-linking method

The structure of cross-linked power cables and the cross-linking method

A conductor is an object that can conduct electric current, also known as a conductive core. The material used as the conductor of the wire and cable must first have good conductivity, that is, the resistance should be small to reduce the loss of the current on the line. The loss is directly related to the magnitude of the current and resistance, and is manifested in the heat generation of the conductor.

The main role of cable armoring and stranding

The main role of cable armoring and stranding

Armoured cable refers to the cable with a metal material armor protective layer, the purpose of the cable plus the armor layer is not only to enhance tensile strength, compressive strength and other mechanical protection to extend the service life, but also through shielding protection to improve the cable anti-interference performance.

Why can't high-voltage wires be buried in the ground?

Why can't high-voltage wires be buried in the ground?

Why can't you bury all the high-voltage wires in the ground like urban underground cables, so that you can't do it once and for all, and you are not afraid of many typhoons?
