Stranded Loose Tube Mining

Flame-retardant Cable（MGTS）

3-2 （MGTS） 副本.jpg

Description

The fibers, 250µm, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. Over the tube, water-blocking material is applied to keep the cable watertight. Two parallel steel wires are placed at the two sides. The cable is completed with a polyethylene (PE) sheath.

  

Characteristics

Good mechanical and temperature performance

High strength loose tube that is hydrolysis resistant  

Special tube filling compound ensure a critical protection of fiber

Two parallel steel wires ensure tensile strength

PE sheath protects cable from ultraviolet radiation

Small diameter, light weight and friendly installation

Long delivery length

 

Standards

GYXY cable complies with Standard YD/T 769-2003.

Application: Aerial
