Water tight cable introduction:
Watertight cable is an important part of the sonar equipment, in accordance with the seal is divided into horizontal water tight cable and longitudinal watertight cable two, longitudinal watertight cable is the water blocking glue or foaming waterstop, sheath damage, delay the who in cable internal flow speed, improve equipment reliability. The traditional water tight cable is sealed by the water blocking paste, the water blocking paste is solidified at room temperature, and the structure of each component is tightly combined together to form a solid whole to realize the water blocking effect.
Application field of water tight cable:
Watertight cable applicable to ships, offshore oil platform, deep resource exploration and in the field of high water density, bend resistance and multi core cable, also can be used in various types of submersible motor lead wire, deep telescopic / using drag and drop of wire and cable, submersible pump and a variety of water electrical work is by the water to water supply connection
Characteristics of watertight cable:
Water tight cable can be in deep water, especially in deep water, which can be used in deep water. Insulating layer uses polyethylene, PVC, or polyvinyl fluorinated ethylene propylene sealant is not flowing sealing glue sheath using chlorinated polyethylene materials due to the invention insulation products with PE or PVC material and an outer sheath using chlorinated polyethylene material, which makes the invention of cable has low smoke, low toxicity, good elasticity and can natural crosslinking and has the advantages of good water blocking effect in the air.
