Submersible Cables for Industrial and Domestic Use

Currency Cables 3 Core Flat Submersible Cables are specially manufactured to supply uninterrupted power to submersible pump motors operating deep underground in wells, boreholes, and flooded irrigation sumps. Built with high-purity, bright annealed Class 5 electrolytic bare copper conductors, each core is insulated with a specialized water-resistant, non-hygroscopic PVC/XLPE compound and encased in a tough, impermeable outer sheath. Engineered to comply strictly with IS 694 and IS 8130 benchmarks, these flat cables endure continuous hydrostatic pressure, fluctuating sub-soil water conditions, dissolved minerals, and severe mechanical pulling tension.

Features & Key Benefits

Impermeable Water & Moisture Barrier: Formulated with non-hygroscopic polymer insulation that prevents water ingress even under prolonged high hydrostatic pressure.

99.97% Pure Electrolytic Bare Copper: Guarantees peak electrical conductivity, preventing pump motor overheating and reducing energy consumption during continuous duty cycles.

Abrasion & Grease-Resistant Sheath: Resists abrasive borehole rock friction, mud, mineral sediments, grease, and acidic or alkaline groundwater.

High Flexibility & Mechanical Strength: Class 5 fine-wire stranding facilitates easy feeding into narrow borehole casings without kink-induced conductor fractures.

Distinct Core Identification: Color-coded in standard Red, Yellow, and Blue for quick, error-free wiring and reliable motor phase balancing.

Frequently Asked Questions

A flat profile allows the cable to fit snugly inside narrow borehole casing pipes alongside the delivery pipe, preventing pinching, twisting, or snagging against the well walls during pump lowering or retrieval. It also simplifies clamping along the riser pipe.

Currency Submersible Cables utilize a non-hygroscopic, high-grade PVC insulation compound extruded with automated laser wall-thickness monitoring. This formulation does not absorb water or swell, preserving high insulation resistance and dielectric integrity under continuous hydrostatic pressure.

Core sizing depends on motor horsepower (HP) and depth of installation to keep voltage drop under 3%: - 1.5 sq. mm to 2.5 sq. mm: Recommended for 1.0 HP to 3.0 HP pumps at moderate depths. - 4.0 sq. mm to 6.0 sq. mm: Standard for 5.0 HP to 7.5 HP pumps or deep bore installations. - 10.0 sq. mm to 35.0 sq. mm: Used for heavy industrial and agricultural pump motors (10 HP to 30+ HP) to prevent starting voltage drops.

Yes. The tough outer PVC sheath is formulated to resist chemical degradation from common groundwater minerals, fertilizers, and mild acids or alkalis. Its abrasion-resistant composition also shields the core from abrasive slurry and sand common in agricultural boreholes.

In addition to routine conductor resistance and spark tests, our laboratory subjects sample lengths to a Water Immersion & High-Voltage Dielectric Test, where the cable is submerged in a water bath at specified temperatures and voltages to confirm zero leakage current and complete dielectric barrier integrity.
