Medium Voltage Cable Insulation Class 100% 133% ICEA S-94-649

Built for performance – 100% & 133% MV insulation grade.

Reliable medium voltage cables for critical power systems.

High dielectric strength, long-lasting protection.

MV cables with 100% & 133% insulation – safety guaranteed.

Certified medium voltage cables for underground & industrial use.

Application

100% and 133% insulation grade medium voltage (MV) power cables are designed for reliable power transmission in utility, industrial, and commercial distribution systems. They feature copper or aluminum conductors insulated with cross-linked polyethylene (XLPE), offering excellent dielectric strength, thermal stability, and long-term performance.

The 100% insulation grade is intended for grounded systems, where the cable operates with minimal overvoltage risk. The 133% grade is used in ungrounded or resistance-grounded systems, offering enhanced insulation thickness to withstand higher electrical stress and improve system reliability under fault conditions.

These cables support continuous operation at 90°C, with short-circuit temperature ratings up to 250°C, and are resistant to moisture, chemicals, and UV exposure. Optional shielding (e.g., copper tape, concentric wires) and PVC or PE outer sheaths provide additional protection and EMI reduction.

Specifications

Aspect	Details & Applications
Conductor Material	Annealed copper or aluminum, solid or stranded, per IEC 60228 / ASTM B8
Insulation Material	XLPE (Cross-linked Polyethylene) or EPR (Ethylene Propylene Rubber) – for high dielectric strength and thermal stability
Insulation Grade	100% level: For systems with effectively grounded neutral133% level: For systems with ungrounded or intermittently grounded neutral
Voltage Range	Typically from 5 kV to 35 kV
Cable Type	Unarmoured or armoured, with metallic shield (copper tape or wire)
Sheath Material	PVC or LSZH (Low Smoke Zero Halogen) – protects against UV, chemicals, and mechanical damage
Standards	ICEA S-93-639 (NEMA WC74), ICEA S-97-682, IEEE 383, IEC 60502-2, AEIC CS8
Electrical Properties	High dielectric strength, low partial discharge, stable under long-term loading
Temperature Rating	90°C continuous operation; up to 250°C in short circuit (5 sec)
Shielding	Metallic shield ensures proper fault current path and controls electric field
Typical Applications	– Power distribution in utilities, industrial zones, substations- Installed in duct banks, conduits, direct buried or trays
Selection Tip	Use 100% insulation for grounded systems (more economical)Use 133% insulation where fault clearance may be delayed
