FAQ From Customers

What is a rubber cable?

A rubber cable is an electrical cable with a rubber insulation that provides flexibility, durability, and safety in various industrial and commercial applications. The rubber insulation offers excellent protection against abrasion, moisture, and high temperatures, making it suitable for use in harsh environments. These cables are commonly used for power transmission, control circuits, and flexible wiring solutions where high performance and long-lasting durability are required.

What is rubber cable used for?

Rubber cables are used for power distribution and signal transmission in industrial, commercial, and residential electrical systems. They are commonly used in applications that require flexible wiring, such as machinery and mobile equipment, construction sites, and electrical installations in environments with high mechanical stress, extreme temperatures, or moisture. Rubber cables are ideal for situations where standard cables might not withstand tough conditions.

What is the difference between rubber cable and flexible cable?

The main difference between rubber cables and flexible cables lies in the insulation material. While both types of cables are designed to handle movement and bending, rubber cables have a rubber-based insulation, offering superior abrasion resistance, flexibility, and weather resistance, making them ideal for harsh environments. Flexible cables, on the other hand, may use materials like PVC or TPE (thermoplastic elastomer) for insulation, which are more suitable for light-duty applications where flexibility is needed but not as much environmental protection.

What are the different types of rubber cables?

There are several types of rubber cables, each designed for specific applications:
Heavy-duty rubber cables: Used in industrial settings for high power transmission and machinery wiring.
Flexible rubber cables: Designed for mobile equipment or dynamic environments where the cable needs to bend or flex.
Rubber insulated power cables: Used for high voltage or low voltage power distribution in both outdoor and indoor installations.
Rubber sheathed cables: Offering extra protection against abrasion and chemical exposure, often used in construction and mining operations.

What are the advantages of using rubber cables?

The main advantages of using rubber cables include their durability, flexibility, and resilience in tough environments. Rubber insulation protects the cable from abrasion, moisture, extreme temperatures, and chemical exposure, making them ideal for industrial and outdoor applications. Additionally, rubber cables offer high flexibility, allowing for easy installation in tight spaces and dynamic environments. These cables also have superior electrical performance, ensuring safe and reliable power and signal transmission over time.
