Protect your high-voltage power infrastructure with our Cable Sheath Protector, engineered to safeguard 35kV, 66kV, 110kV, and above single-core cables from damaging induced overvoltages. Compliant with DL/T401-1991 standards, this essential device prevents insulation breakdown by limiting lightning surges, internal overvoltage waves, and fault-induced stresses on the cable’s metal sheath. By grounding transient voltages at the unshielded end, it eliminates risks of multi-point grounding failures, ensuring stable grid operation and extending cable lifespan. Ideal for substations, renewable energy farms, and industrial power networks, our protector delivers robust performance under extreme conditions. Reduce downtime, comply with regulations, and secure your investments with reliable overvoltage protection.
