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. The tube is wrapped with a layer of PSP longitudinally. Between the PSP and the loose tube water-blocking material is applied to keep the cable compact and watertight. Two parallel steel wires are placed at the two sides of the steel tape. The cable is completed with a flame-retardant 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

Special sheath material ensures excellent flame-retardant performance

Crush resistance and flexibility

PSP enhancing moisture-proof

Two parallel steel wires ensure tensile strength

Small diameter, light weight and friendly installation

Long delivery length

  

Standards

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

Application: Duct / Aerial

Note：

a. Suffix Xn denotes fiber type .

b. The colour arrangements of fiber and tube are specified in the colour identification table.

c. The nominal value of the flame-retardant PE sheath minimum thickness outside of the strength member is 1.0mm.

d. The steel tape is not corrugated in the cable with 12 fibers below. If the corrugated steel tape is requested, it should be specified in contract.
