Structure Design:

Applications:
● Replacement of existing ground wires and reconstruction of old lines.
● Applicable to low-grade lines, such as GJ50/70/90 and etc.
Main Features:
● Small cable diameter, light weight, low additional load to the tower;
● The steel tube locates at the center of the cable, no second mechanical fatigue damage.
● Low resistance to side pressure, torsion and tensile (single layer).

Remarks:
Detail requirements need to be sent to us for cable design and price calculation. Below requirements are a must:
A, Power transmission line voltage level
B, fiber count
C, Cable structure drawing & diameter
D, Tensile strength
F, Short circuit capacity
Type test
Type test may be waived by submitting makerʼs certificate of the similar product performed in an internationally acknowledged independent test organization or laboratory. If type test should be performed, it will be carried out according to an extra type test procedure reached to an agreement between purchaser and manufacturer.
Routine test
The optical attenuation coefficient on all production cable lengths is measured according to IEC 60793-1-CIC (Back-scattering technique, OTDR). Standard single-mode fibers are measured at 1310nm and at 1550nm. Non-zero dispersion shifted single‒mode (NZDS) fibers are measured at 1550nm.
Factory test
Factory acceptance test is carried out on two samples per order in the presence of the customer or his representative. The requirements for quality characteristics are determined by relevant standards and agreed quality plans.
