3 CORE FLAT SUBMERSIBLE CABLE

A 3 core flat submersible cable is a heavy-duty electrical cable designed for powering submersible pumps and motors, typically used in agriculture, domestic water systems, and industrial settings.​

Key Specifications

• Construction: 3 parallel copper conductors, each insulated and encased in a tough, water-resistant PVC sheath for durability and protection against abrasion and moisture.​

• Core Colours: Typically red, yellow (center), and blue, for clear phase identification.​

• Voltage Rating: Up to 1100V.​

• Sizes: Common cross-sectional areas include 1.5mm², 2.5mm², 4mm², 6mm², 10mm², and beyond; selected based on the pump’s current requirement and installation conditions.​

• Current Ratings: For example, a 2.5mm² cable can generally carry up to 18–22A at 40–45°C, while a 4mm² cable can handle up to 26–28A depending on manufacturer and site conditions.​

• Temperature Resistance: Variants are available for 70°C and 85°C operation; derating factors apply for higher ambient temperatures.​

• Length: Supplied in standard coils (often 100m) or customized lengths as required.​

Applications

• Ideal for connecting submersible pumps in borewells, open wells, and deep wells for irrigation, drinking water, dewatering, and industrial water transfer tasks.​

• Used in agricultural fields, irrigation systems, and water supply systems where cables are exposed to continuous water immersion or damp environments.​

Technical Features

• Materials: High-conductivity, multiple-stranded, electrolytic annealed copper for supreme flexibility and minimal power loss.​

• Sheathing: Special PVC compound ensures excellent resistance to water, oils, chemicals, and abrasion, necessary for underground and submerged environments.​

• Flat Design: Prevents cable tangling during installation and retrieval; fits snugly into narrow bores and spaces.​

Important Notes

• Select the cable size based on pump load (current), installation length, and site conditions to avoid voltage drop and ensure long-term reliability.​

• Ensure cables carry valid ISI certification and meet relevant standards for safety.
