JFPYH submersible watertight 6-core cables
Type：JFPYH 500V
Rated voltage：500V
Temperature Range: -30℃~ 90℃
conductor：Class 5 silver-plated copper
Insulation: Polyperfluoro Ethylene Propylene (FEP)
Braid: tinned copper braid and AL Foil Overlap
Sheath: chlorosulfonated polyethylene (CSP)
Standard： GJB 773A/8A-2000
Application：JFPYH submersible watertight cables are twisted in pairs and designed with a copper braid screen to avoid EMC interference with CSP sheath. The conductor consists of stranded silver-plated copper wire and their lateral pressure resistance can achieve 6Mpa that ensure the good signal transmission. CSP sheath also provide excellent resistance of seawater impregnation and surface abrasion.
