Rubber Cable
Long before PVC and PE were invented, rubbers were used to insulate cables because of their low electrical conductivity. Natural rubber was initially used but later it was replaced by synthetic rubber. Rubber cables do not soften or melt at higher temperatures as they are thermoset materials. These materials are cross-linked through the vulcanization process and hardened rubber cables perform stable under all conditions.
We can modify the characteristics of electrical wires coated with rubber by modifying the elements in the basic material. The modifying elements are added to the raw material as antioxidants, fillers, hardening agents, accelerators, and antiozonants. With these changes, the cables gain flexibility at different temperatures and higher water absorption capabilities. Due to their superior absorption capacity, excellent performance against weather, and good abrasion-resistant qualities, rubber-insulated cables are ideal for use in extreme environments.
A common type of cable with a rubber sheath is black in appearance with one or more rubber-insulated conductors within. With this configuration, the cable has a waterproof electrical coating which provides adequate insulation for the conductors. Flexible rubber cables are expected to withstand bending, friction, torsional, and other mechanical forces applied. They are designed to be used outdoors and perform against moisture, aging in sunlight, and exposure to oil.
Rubber-insulated wires have a smaller overall diameter and are easy to use. The individual wires and cables in a larger construction are insulated by the rubber coating. Based on the materials used, rubber-coated cables can be further divided into:
-
Tough rubber sheathed cables use thermoplastic rubber as an insulating material. It enables higher processing speed and a wider temperature range but limited cut-through resistance.
-
Rubber electrical cable coating can be done by neoprene; a thermoset rubber material. It provides excellent cut-through, abrasion, oil, and solvent resistance as well as fire-resistant performance and a long operational life.
-
Silicone is another coating material for rubber-insulated wires; famous for flame and heat resistance.
-
For low-voltage insulation of rubber cables; chloro sulfonated polyethylene is used. It offers a wide temperature range capability and high resistance against chemicals and UV rays.
These is not all; there are different types of rubber cables manufactured in India. Besides these, we also produce NBR cables. Some of them are manufactured for double insulation, like 2 Core Rubber Flex which can be used on light fittings without any metal parts. For single-core wires with better heat resistance, an h07g-k wire can be ideal. It is manufactured from high-quality bare copper and standard tin content. We have many years of experience in manufacturing these types of wires but our dedication to quality and competitive price made us one of the top rubber cable manufacturers in India.
