A new glass steel cable bracket with SMC manufacturing process, is a sheet made of paste resin impregnated glass fiber unsaturated polyester reinforced plastics, GF (glass fiber), UP (unsaturated resin), MD (filler) and low cut sheet molding composition of various additives and binder additives. SMC glass fiber reinforced plastic cable support is a kind of thermosetting composite material. It is limited by SMC composite material at high temperature. The content of alkali free glass fiber R2O is less than 0.8%, which is a kind of aluminum borosilicate component. Its chemical stability, electrical insulation, and strength are excellent. It is mainly used as an enhancement material for electrical insulation materials and glass fiber reinforced plastics. In short, SMC cable holder has superior electrical function and corrosion function, lightweight, simple design, flexible mechanical function and can compare with some metal materials, the product of high surface smoothness, low shortened additives, the appearance quality is more ideal.
1, natural insulation: stent insulation function is good, no need to ground, excellent resin with flame retardant data, arc resistance and resistance to leakage trace index (PTI) high.
2, surface lubrication: the friction coefficient is small, no scratch damage cable break.
3, super corrosion resistance: in acid, alkali, salt environment, no corrosion, no rust, no mildew.
4, flame retardant fire: heat-resistant, cold resistant. Fire protection function is excellent, flame retardant function is good, burning rate (level 25, smoke density is less than or equal to 500), oxygen index reaches more than 29, can be used in -40 to 150 degree Celsius, safe and reliable.
5, strong bending resistance: no creep, in the wet, high fever, cold environment, mechanical strength maintained above 95%, even in a long time under load is not deformation, the mechanical strength of the cable can accept more outstanding, complete the longer vacant interval.
6, prevent Vortex: current flow through the cable process will occur magnetic field, composite data of high insulation, prevent magnetic field and stent constitute closed loop, circulation.
7, light, high strength, as long as the weight of the steel bracket 1 / 4, concrete bracket 1 / 10 or so, construction simple. Easy transportation;
8, long life: 50 years underground, the ground 25 years, long life, durable, safe and nontoxic,
9, environmental protection anti-theft: FRP material safety, environmental protection, non-toxic, and no recovery value, fundamentally solve the problem of theft.
