Rubber insulated cable (N)SSHOEU /3E

(N)SSHOEU / 3E Rubber Insulated Cable — Medium Voltage Mining & Heavy Industrial

(N)SSHOEU is a German VDE standard medium-voltage rubber-insulated flexible cable specifically designed for mining, quarrying, and heavy industrial applications requiring continuous flexing under harsh conditions. EPDM or EPR rubber insulation provides high dielectric strength, conductive screens protect against earth faults, and a robust neoprene outer sheath ensures durability. Rated voltages from 1 kV up to 6 kV; operating temperatures ‑40°C to +90°C.

Key Design Features

• EPDM / EPR rubber core insulation with high dielectric strength
• Conductive rubber screen over each core for earth fault protection
• Overall copper wire screen for symmetrical capacitance
• Oil and weather-resistant rubber outer sheath
• Optional /3E Earth monitoring conductor for personal safety
• Rated 1 kV to 6 kV; temperature ‑40°C to +90°C
• Compliant with VDE 0250 / IEC 60245 mining cable requirements

Selection Guide

Importance of the /3E Earth Monitoring Option

The /3E variant adds dedicated earth monitoring conductors connected to an insulation monitoring relay — mandatory in many mining regulations and IEC 60364-7-706 installations in restrictive conductive locations.
