IEC 61111 Compliant Electrical Insulation Rubber Sheet
Engineered for high-voltage dielectric protection, our insulation rubber sheet is formulated from premium non-conductive synthetic rubber compounds. Specifically designed to insulate floors, machinery bases, and high-voltage control rooms, this electrical insulation rubber sheet provides an essential safety barrier against electrical shock in power generation, substation maintenance, and industrial facility management.
Smooth Surface Finish for Superior Contact & Easy Maintenance
Unlike textured or ribbed insulating mats, this high-voltage insulation rubber sheet features a precision smooth surface finish on both sides. The flat design guarantees seamless surface contact with switchboard floors and cabinet foundations while eliminating dirt-trapping grooves. This smooth finish allows effortless cleaning, routine safety inspections, and seamless placement of heavy electrical equipment without tearing or uneven wear.
Certified Dielectric Protection & Industrial Applications
Manufactured under strict quality controls to meet IEC 61111:2009 international standards (Class 0 through Class 4), each batch undergoes rigorous dielectric withstand testing (up to 50kV). Outstanding resistance to moisture, oils, ozone, and mechanical compression makes our electrical insulation rubber sheet the preferred safety solution for:
- High-Voltage Switchgear Rooms: Safety floor matting in front of high-voltage circuit breakers and control panels.
- Substations & Transformer Zones: Non-conductive floor protection during live electrical line repair and transformer servicing.
- Industrial Power Cabinets: Dielectric insulation lining for power distribution units and motor control centers (MCC).
- Electrical Maintenance Workbenches: Custom cut-to-size insulating pads for benchtop electrical testing and tool assembly.
