Silicone rubber injection insulation tubular bus

Abstract

The invention discloses a silicone rubber injection insulation tubular bus which comprises a metal copper pipe, a dimethicone layer, a flame-retardant layer, a fluororubber layer and a thermal contraction layer, the flame-retardant layer is arranged on the outer side of the dimethicone layer, and the fluororubber layer is arranged on the side, away from the dimethicone layer, of the flame-retardant layer. According to the invention, by arranging the chlorosulfonated polyethylene layer and the chloroprene rubber layer, the flame-retardant effect is achieved, by arranging the magnesium hydroxidelayer, the effect of improving the flame retardancy is achieved, by arranging the dimethicone layer, the effects of oxidation resistance, thermal resistance, electric insulativity and weather resistance are achieved, by arranging the thermal contraction layer, a thermal contraction function, electrical insulation, physical and mechanical properties and chemical corrosion resistance are achieved,by arranging an insulating sleeve layer, the effect of improving the insulativity is achieved, and the problems that the quality of the tubular bus is uneven, the insulating and flame-retardant effects of certain tubular buses are poor, and the service life of the buses is shortened are solved.

Description

technical field [0001] The invention relates to the technical field of busbars, in particular to a silicone rubber injection insulating tubular busbar. Background technique [0002] Tubular busbar is a kind of busbar product that uses copper tube or aluminum alloy tube as conductor and external insulation. It is called tubular cable abroad. , a wide range of applications, etc., so it is recognized and accepted by more and more customers. In foreign countries, this type of product has decades of operating history and experience, while domestically, due to the short time to enter this field and the ability of technology research and development , the limitation of insulating materials and many other reasons, currently only products with a voltage level of 35 kV and below can be produced. At present, this product is still a small industry in China. The country does not have specific and detailed product standards. Generally, each enterprise implements its own Enterprise standa...
