Product Overview

Our Heavy-Duty Rubber Insulated Submersible Pump Cable is engineered for reliable and durable power transmission to submersible motors in demanding aquatic environments. Utilizing Ethylene Propylene Rubber (EPR) insulation and a robust synthetic rubber sheath, this cable is specifically constructed to perform under continuous submersion, high pressure, and exposure to oils and chemicals commonly found in deep-well and borehole applications.

Key Features & Benefits

  • True Submersible Design: Built for continuous operation while fully submerged, capable of withstanding significant hydrostatic pressure in deep-well installations.

  • Superior Material Integrity:

    • EPR Insulation: Offers excellent long-term electrical stability, flexibility, and resistance to heat aging in wet conditions.

    • Synthetic Rubber Sheath (e.g., CSP/CR): Provides outstanding protection against abrasion, water ingress, oils, ozone, and chemicals, ensuring long service life.

  • Enhanced Durability: Excellent mechanical properties including tensile strength and crush resistance to withstand the rigors of installation and operation in confined spaces.

  • Broad Temperature Range: Designed to perform reliably across a wide spectrum of ambient and operational temperatures.

  • Safety Compliant: Incorporates a mandatory Green/Yellow conductor for protective earth, in full compliance with international safety standards.

Construction

  1. Conductor: High-conductivity, finely stranded copper for optimal flexibility.

  2. Insulation: A uniform layer of high-grade EPR compound for dielectric strength.

  3. Filling: Non-hygroscopic materials to form a round, compact core structure.

  4. Binder: A binder tape or yarn to secure the assembled cores.

  5. Sheath: An extruded layer of tough, oil-resistant synthetic rubber for overall protection.

Standards & Compliance

This cable is designed and tested in accordance with leading international standards for elastomer-insulated cables in harsh environments:

  • UL 44 (For Types RHH/RHW-2 suitable for wet locations)

  • IEC 60245-4 (Rubber insulated cables – Cords and flexible cables)

  • BS 6883 (Elastomer insulated cables for fixed wiring in demanding applications)
