Embodiment 1

[0023] In 2015, Dongguan Changan Power Supply Bureau carried out insulation transformation on the distribution network in the area in order to ensure the normal and safe use of electricity by the people. Among them, in the full insulation transformation of 10KV overhead lines, the joints of all wires, the two ends of the joints between overhead lines and cable outdoor terminals are encapsulated with the radiation cross-linked silicone rubber self-melting insulation wrapping sheet of the present invention Insulation treatment: use the radiation cross-linked silicone rubber self-melting insulation package of the present invention to replace all the aging insulation shields on the contacts of high-voltage knife switches, exposed high-voltage porcelain heads of transformers on piles, and transformer fuses. For those without insulation protection The equipment contact of the cover is also encapsulated by the radiation cross-linked silicone rubber self-melting insulating wrapping she...

Abstract

The invention provides application of irradiated crosslinked silicone rubber in insulated reconstruction of a power distribution network. The irradiated crosslinked silicone rubber provided by the invention has no chemical cross-linking agent residue and realizes no environment pollution and high environment-friendly performance. Furthermore the irradiated crosslinked silicone rubber has micro-rebounding performance, viscosity and creep deformation performance. No restriction of the irradiated crosslinked silicone rubber as an insulating packaging strip in a use process by irregular shape of an equipment contact is ensured. Along with use time increase, an adhesion force increases and no easy falling is realized. In long-term use in a high-temperature and ultraviolet ray environment, conditions such as aging and cracking, and loosening and falling caused by the chemical crosslinking agent are prevented. Furthermore corrosion, heating and current carrying capability reduction caused bywetness and acid / alkali corrosion of air can be prevented. Safe operation of a power cable can be ensured in high efficiency. Furthermore the cost of the irradiated crosslinked silicone rubber is lower than that of an ordinary protective cover. Furthermore in the use process, high speed and high convenience in mounting are realized. Furthermore recycling is realized.

Description

technical field [0001] The invention relates to the application of an insulating wrapping sheet, and more specifically, relates to the application of irradiation crosslinked silicone rubber as a self-melting insulating wrapping sheet in the insulation transformation of a power distribution network. Background technique [0002] Under the traditional technical conditions, the insulation material of the power grid is based on plastic, coated with various adhesives to form a double-layer or three-layer insulating tape, and an insulating protective cover made of heat-shrinkable material (or silicone rubber material). However, under natural conditions (2-3) years, the insulating tape made of plastic material and the insulating shield of various materials will age rapidly, and the strength, electrical insulation, and corrosion resistance of the insulating tape and insulating shield will decline significantly. , It is easy to loosen, shift, crack, or even fall off from the power ...
