Underwater Testing Cable Good Bending Resistance
- Sep 11, 2017 -

Underwater propeller detection cable is an important part of the sonar equipment, according to the sealing method is divided into horizontal watertight cable and vertical watertight cable two, vertical watertight cable is the use of water-resistant glue or foam water-blocking, The case of delaying the speed of movement within the cable, improve the reliability of the equipment used. The traditional watertight cable is sealed with water-blocking paste, and the water-blocking paste is cured at room temperature, and the components are tightly integrated together to form a solid whole to realize the water blocking effect.

Underwater propeller detection cable Applications:

Underwater propeller detection cable for ships, offshore oil platforms, deep sea resource detection and other areas of high watertight, resistant to winding multi-core integrated cable, but also for all types of submersible motor lead wire, deep water in the telescopic / drag The use of wire and cable, submersible pumps and a variety of underwater work appliances from the water to the water power connection.

Underwater propeller detection cable Features:

1. Signal transmission stability, strong conductor toughness: stranded copper wire twisted, pure copper.

2. Anti-interference ability: double shield, 1. Aluminum foil shielded 2. Tinned copper mesh weaving

3. Good bending resistance: PVC towline dedicated cable ≤ 300 million times PUR towline dedicated cable ≤ 600 million times

4. Excellent tensile strength: Kevlar fiber filled, according to customer requirements to increase the tensile strength.

5. Temperature resistance is good: 1. PVC towline dedicated cable -15 ℃ ~ +70 ℃; towline dedicated network cable -40 ℃ ~ +70 ℃.

6. Good wear resistance: special production technology and quality outer jacket material.
