EPR INSULATION 90 °C, FROM 5 kV TO 25 kV

WITH TWO GROUNDING CONDUCTORS AND ONE GROUND-CHECK CONDUCTOR

CHLORINATED POLYETHYLENE JACKET(CPE)

1. Annealed Copper Conductors (Class B): High-quality copper wires that are soft and flexible for better conductivity.

2. Extruded Conductor Shielding: A protective layer around the conductor to reduce electrical interference.

3. EPR (Ethylene-Propylene Rubber) Insulation: A durable, flexible, and heat-resistant rubber layer that provides insulation.

4. Extruded Insulation Shielding: A protective layer over the insulation to improve safety and performance.

5. Combination Annealed Tinned Copper: A mix of soft copper wires with a tin coating to resist corrosion.

6. Colored Textile Thread over Individual Phase Conductors: Color-coded threads to help identify different wires.

7. Soft Copper Ground Check Conductor: A flexible copper wire used for safety monitoring.

8. Mylar Tape: A thin, protective wrapping that enhances cable durability.

9. Yellow EPR Insulated Ground Check Conductor: A special safety wire insulated with yellow rubber for easy identification.

10. Stranded Annealed Uninsulated Plain Bare Copper Ground Wires: Soft, uncoated copper wires used for grounding.

11. Rubber-Faced Binder Tape: A protective rubberized tape that holds the cable layers together.

12. Chlorinated Polyethylene (CPE) Jacket: A tough outer layer that resists chemicals, moisture, and wear.
