2752(2751)硅橡膠玻璃纖維軟管(符合滬Q/JBQR5-2000)
2752(2751) Fiberglass Sleeving coated With Silicone Rubber (In According With Shanghai Q/JBQR5-2000)
是由無(wú)堿玻璃纖維編織成套管,然后涂以硅橡膠,經(jīng)加熱硫化而成的絕緣套管。本產(chǎn)品具有一定的介電性能,較高的耐熱性、優(yōu)良的耐寒性和富于彈性,適用于H級絕緣電機、電器的布線(xiàn)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.
