耐高温套管高品质质量
耐高温套管由高品质无碱玻璃纤维纱编织成管后，涂以**耐高温硅树脂经高温处理而成。耐高温套管具有阻燃、隔热、保温、抗电、柔软等性能。耐高温套管主要应用于钢铁厂、冶炼厂、玻璃厂、消防设备、大型变压场所等高温场所的电缆绝缘保护。
高温防护套管广泛应用于电力、化工、冶金、船舶、机械制造及其它行业的高温区域;冶金企业加热区电缆、流体管路、进给快换接头、轧制区辊道、轧机电缆、油管;锯切周边电缆、油管及接头;钢包车电缆包覆等等领域.
耐高温套管性能测试：
高温折曲测试
在260℃之恒温炉中加热48小时后表面无老化破裂或涂膜表层无剥离现象产生
低温折曲测试
在-70℃之恒温炉中加热1小时后表面无破裂或涂膜表层无剥离现象产生。
涂膜被覆测试
经恒温炉连续使用测试后无表面脱落或溶解现象产生。
燃烧测试
难燃自熄及无自燃现象(符合UL"VW-1" and CSA "HFS" 测试)
阻燃性测试
燃烧速度不小于45s/25mm —- SRG-1-7kv SRG-1-4kv，(电机绝缘等级可达到比H更高的C等级)
常态较低绝缘破坏电压 7.0 kv /min 4.0 kv / min
常态平均绝缘破坏电压 10.0 kv/ min 7.0 kv / min
耐高温套管具有以下特性：
安全环保，保护工人身体健康
无碱玻璃纤维本身具有拉力特强，不会皱折断、耐硫化、无烟无卤无毒、纯氧不燃、绝缘好的特性，再经**硅胶固化后，更加强其安全环保性能，有效保护工人人体健康，降低职业病的发生率。不像石棉制品等对人体及环境危害性较大。

High temperature resistant casing made of high -quality E-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.
Widely used in high-temperature high-temperature protective sleeve regional 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 .
High temperature performance test tube :
High temperature bending test
Aging of the coating surface without cracking or peeling skin produces no heating at a constant temperature of 260 ℃ oven for 48 hours
Cold bending test
After heating at a constant temperature of -70 ℃ oven for 1 hour surface without cracking or peeling produce no surface coating .
Film -coated test
After continuous use by the thermostatic oven off or dissolved test without surface phenomenon .
Combustion Testing
Flame retardant and self-extinguishing no spontaneous combustion phenomena ( meets UL "VW-1" and CSA "HFS" test )
Flammability Testing
Burning rate of not less than 45s/25mm - SRG-1-7kv SRG-1-4kv, ( motor insulation levels can reach higher than the H C grade )
Normal minimum breakdown voltage 7.0 kv / min 4.0 kv / min
The average normal breakdown voltage 10.0 kv / min 7.0 kv / min
High temperature resistant casing has the following features :
Safety and environmental protection , protection of workers' health
E-glass fiber itself has a particularly strong rally , will not wrinkle break resistance, curing , smoke halogen-free , non-toxic , non-flammable pure oxygen , good insulation properties, and then after curing silicone , has strengthened its safety and environmental performance, effective protection workers' health , reduce the incidence of occupational diseases. Unlike asbestos products such great harm to humans and the environment .
