Ideal for replacing existing ground wires and upgrading aging transmission lines.
Suitable for use on lower-grade lines such as GJ50/70/90, among others.
Compact cable diameter and lightweight design minimize additional load on towers.
Centralized steel tube construction prevents secondary mechanical fatigue damage.
Offers low resistance to lateral pressure, torsion, and tensile forces (single-layer structure).

To facilitate cable design and accurate pricing, please provide the following essential information:
A. Voltage level of the power transmission line
B. Required fiber count
C. Cable structure diagram and overall diameter
D. Required tensile strength
E. Short-circuit current capacity
Type testing may be exempted if the manufacturer provides certificates for similar products tested by an internationally recognized and independent testing organization or laboratory.
If type testing is required, it will be conducted based on a mutually agreed-upon test procedure between the purchaser and the manufacturer.
Optical attenuation coefficients are measured on all production cable lengths in accordance with IEC 60793-1-CIC using the backscattering (OTDR) method.
Standard single-mode fibers are tested at wavelengths of 1310 nm and 1550 nm, while non-zero dispersion-shifted (NZDS) fibers are tested at 1550 nm.
Factory acceptance testing is performed on two cable samples per order, witnessed by the customer or their representative.
The quality requirements and evaluation criteria are based on applicable standards and pre-agreed quality plans.
