Description
a. Many cable intermediate joint faults are caused by poor sealing. Our company adopts a new process (three-seal process), making cable operation safer and more reliable. The so-called three seals are: outer sheath seal, inner sheath seal, plus seals at both ends of the inner insulating tube, for a total of three seals. b. The insulating tube is lengthened, solving the creepage problem. c. The protective sleeve is soft and flame-retardant.
