详细说明:PUG-301

2741聚氨酯玻璃纤维软管(符合沪Q/JBQR23-2001) 

2741 Fiberglass Sleeving Coated With Polyurethane (In According With Shanghai Q/JBQR23-2001)  

    聚氨酯玻璃纤维软管系采用无碱玻璃纤维编织成管,并涂以改性聚氨酯树脂经加热烘干而成的F级绝缘软管。具有可靠的耐热性,良好的电性能,较好的柔软性和弹性。适用于做F级电机、电器及仪表、无线电、家用电器等装置的布线绝缘和机械保护。

   长度:1000( )毫米(连续长度由供需双方协议)。 

 

    Fiberglass sleeving coated with polyurethane is manufactured with non-alkali fiberglass braided sleeving and coated with a layer of polyurethane and than thermoset to form F grade insulating sleeving.It possesses reliable heat resistance,good qualities of dielectric,fair softness and elasicity.It can be used for wiring insulation and machanic protection for F grade electrical machinery,electric appliances,electrical instruments,wireless sets and domestic electrical appliances.

    Length:1000( )mm(continuous length can be negotiated).
