4 Core Copper Flexible Rubber Cable for Submersible Pumps (JHS / YC / YCW Waterproof Power Cable)

In industrial, agricultural, and water management systems, reliable power supply for submersible equipment is critical. One of the most widely used solutions is the 4 core copper flexible rubber sheathed cable, commonly known as JHS submersible pump cable or YC/YCW heavy-duty rubber cable.

Designed for harsh and wet environments, this cable provides excellent waterproof performance, flexibility, and electrical stability, making it ideal for submerged and outdoor applications.

1. What is a 4 Core Rubber Sheathed Flexible Cable?

A 4 core copper flexible rubber cable is a type of heavy-duty power cable consisting of:

• Multiple copper conductors (typically 4 cores)

• Rubber insulation and sheath

• High flexibility structure

It is widely used in:

• Submersible pumps

• Industrial equipment

• Construction machinery

• Outdoor and mobile power systems

2. JHS Submersible Pump Cable – Specialized Waterproof Solution

The JHS cable is specifically designed for long-term underwater operation.

Key Features:

• Fully waterproof rubber insulation

• Suitable for continuous immersion in water

• Excellent resistance to oil, abrasion, and chemicals

• Stable performance under mechanical stress

Typical Applications:

• Deep well pumps

• Sewage pumps

• Aquaculture systems

• Flood control and drainage systems

Compared with standard rubber cables, JHS cables offer superior sealing and water resistance, ensuring long service life even in extreme conditions.

3. YC / YCW Heavy-Duty Rubber Cables

YC Cable

• General-purpose heavy rubber cable

• Suitable for dry or slightly wet environments

YCW Cable

• Enhanced version of YC

• مقاوم للماء (water-resistant) and weather-resistant

• Suitable for outdoor and harsh environments

Key Advantages:

• High mechanical strength

• Flexible bending performance

• مقاومة التآكل (abrasion resistance)

• Good electrical conductivity

4. Cable Structure and Technical Specifications

Conductor

• Material: High-purity copper (bare or tinned copper)

• Structure: Fine-stranded for flexibility

Core Configuration

• 4 core design (3 phase + 1 ground or neutral)

Insulation

• Rubber (EPR or similar elastomer materials)

Outer Sheath

• Durable rubber sheath

• Waterproof and UV resistant

Voltage Rating

• Typically: 300/500V or 450/750V
