2752(2751)硅橡胶玻璃纤维软管(符合沪Q/JBQR5-2000)

2752(2751) Fiberglass Sleeving coated With Silicone Rubber (In According With Shanghai Q/JBQR5-2000)

硅橡胶玻璃纤维软管是由无碱玻璃纤维编织成套管，然后涂以硅橡胶，经加热硫化而成的绝缘套管。本产品具有一定的介电性能，较高的耐热性、优良的耐寒性和富于弹性，适用于H级绝缘电机、电器的布线绝缘和机械保护。

注：内径1.5毫米及以下的软管，击穿电压不得低于规定值的75%。

Fiberglass sleeving coated with silicone rubber produced with the process of thermal treatment and vulcanization is the non-alkli fiberglass braided sleeving coated with silicone rubber.This sleeving possesses good qualities of dielectric,high temperature resistace,excellent elasticity and cold resistance.It can be used for wiring insulation and mechanical protection for H grade electrical appliances.

Note:The breakdown voltage for sleevings whose inner diameter is or be low1.5mm should not than 75% of the specified voltage.
