Type：JFPYH 500V
Rated voltage：500V
Temperature Range: -30℃~ 90℃
conductor：Class 5 tinned 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 designed with a copper braid screen to avoid EMC interference with CSP sheath. Their lateral pressure resistance can achieve 4.5Mpa that ensure the good signal transmission. CSP sheath also provide excellent resistance of seawater impregnation and surface abrasion.
