2752（2751）硅橡膠玻璃vr1.5分彩計劃纖維軟管（符合滬Q/JBQR5-2000） 

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

    是由無堿玻璃纖維編織成套管，然后涂以硅橡膠，經加熱硫化而成的絕緣套管。本產品具有一定的介電性能，較高的耐熱性、優良的耐寒性和富于彈性，適用于H級絕緣電機、電器的布線絕緣和機械保護。 

   注：內徑1.5毫米及以下的軟管，擊穿電壓不得低于規定值的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.
