The 35kV High-Quality ABC Cable sets a new benchmark for reliability in substation applications, combining exceptional electrical performance with rugged durability. Designed to withstand 50 kA/1s short-circuit currents—a critical safety feature for substation environments—this cable features weatherproof insulation and a compact design that reduces installation space by 30% compared to traditional substation cables.
A tinned copper shield provides superior EMI (Electromagnetic Interference) and RFI (Radio Frequency Interference) protection, ensuring stable operation in electrically noisy environments. Fully compliant with IEC 60502 and IEEE 404 standards, it has become the preferred choice for urban power grids, renewable energy substations, and industrial distribution networks where reliability and space efficiency are paramount.
Parameter | Value |
Rated Voltage | 35 kV |
Conductor Material | Tinned Copper |
Insulation Resistance | ≥100 GΩ at 20°C |
Short-Circuit Current | 50 kA/1s |
Sheath Material | XLPE |
Weatherproof Construction
The cable’s insulation is composed of cross-linked polyethylene (XLPE), a material renowned for its resistance to moisture, UV radiation, and chemical exposure. Combined with a UV-resistant outer sheath and IP68 ingress protection rating, this construction ensures the cable remains operational for 40+ years in outdoor and underground substation environments, including coastal areas with high salt content.
High Short-Circuit Capacity
The tinned copper conductor—chosen for its excellent conductivity and corrosion resistance—works in conjunction with an aluminum alloy armor layer to withstand extreme thermal and mechanical stresses during short-circuit events. This ensures the cable maintains integrity during faults, preventing catastrophic failures and reducing downtime for repairs.
Space-Saving Design
With a compact diameter of ≤60 mm, the cable simplifies routing in congested substation environments where space is limited. This reduces installation complexity and costs by 15%, as fewer modifications to existing infrastructure are required to accommodate the cable. The flexible design also allows for a bending radius of 10× cable diameter, facilitating installation in tight spaces.
Substations: Used for indoor and outdoor connections in transmission and distribution substations, linking transformers, circuit breakers, and busbars with reliable, low-loss power transmission.
Renewable Energy: Integral to collection systems in solar farms and wind parks, where the cable’s weather resistance and high current capacity support efficient power aggregation and grid connection.
Industrial: Connects heavy machinery and distribution panels in mining, manufacturing, and petrochemical facilities, withstanding the harsh operating conditions typical in industrial environments.
Q: What is the bending radius?
A: The cable is designed with a minimum bending radius of 10× its outer diameter, which for a 60 mm diameter cable translates to 600 mm. This flexibility allows for easy installation in confined spaces within substations and around existing equipment without compromising structural integrity.
Q: Does it require special termination kits?
A: Yes, we recommend using our proprietary 35kV pre-molded terminations for optimal performance. These factory-tested terminations ensure proper insulation and shielding continuity, reducing installation time by 50% compared to field-molded alternatives and minimizing the risk of installation-related failures.
