High temperature fiberglass pipe made of high-quality fire-alkali glass fiber yarn woven into a tube and coated with high temperature resistant silicone resin by organic high temperature. High temperature resistant casing with fire retardant, insulation, anti-electric, soft properties. High temperature resistant casing mainly used in steel plants, smelters, glass, fire fighting equipment, large venues and other places of high temperature transformer cable insulation. High temperature fiberglass pipe is widely used in high-temperature zone of fire power, chemical, metallurgy, shipbuilding, machinery manufacturing and other industries; metallurgical enterprises heating zone cables, fluid lines, feeding quick coupler, rolling area roller mill cable ., tubing; sawing peripheral cables, tubing and fittings; coated steel cable car so the field of high temperature glass fiber product descriptions fire performance test tube: high-temperature bending test thermostatic oven at 260 ℃ heating for 48 hours after the free surface aging of the coating surface cracking or peeling phenomenon without bending low heat 1 hour after the test surface without cracking or peeling produce no surface coating at a constant temperature of -70 ℃ in the oven. Thermostatic oven coated film after test after test without continuous use off the surface or dissolved phenomenon. Flame retardant and self-extinguishing flame test no spontaneous combustion phenomena (meets UL "VW-1" and CSA "HFS" test) Temperature Test (2000hr) 260 ℃ heating tests are normal no abnormal (30sec) 1200 ℃ heating test glass fibers intact flame burning speed test is not less than 45s/25mm --- SRG-1-7kv SRG-1-4kv, (motor insulation level up to a higher level than the C-H) normal minimum dielectric breakdown voltage of 7.0 kv / min 4.0 kv / min normal average dielectric breakdown voltage 10.0 kv / min 7.0 kv / min
