Rubber Insulated Cables

Rubber Insulated Cables

Insulated wire, also known as cable, is made of a non-conductive material that does not allow an electric current to flow through it. It surrounds and protects the wire.

Based on the utility, you can find and choose the best-insulated cables for your business here.


Rubber was the first material to be used as insulation and harness material for cables long before polyvinyl chloride and polyethylene became common applications. It remains widely used for industrial and domestic purposes, such as in the following;

  1. Oil & gas sectors
  2. Renewable energy
  3. Docks & dockyards
  4. Airfields
  5. Mining industry
  6. Petrochemical manufacturers
  7. Refineries
  8. Shipbuilding & Marine
  9. Industrial plants & factories

Cables should be strong and sturdy to withstand heavy machinery, often moving in different locations. These cables must use high-quality materials, so they are safe and reliable.

Rubber-insulated wires are used in electrical equipment, light-assist parts, and AC-rated voltage at 500 volts. These wires have a long-term operation temperature of 65 degrees, and most attach to make fixed attachments. The majority of these wires are the BX model with a 0.75 to 6.3 square millimeters cross-section range, conductive wire core for 1-4 cores per individual wire.

Advantages of Insulated Wire and Cable

Rubber cables can be made from Natural Styrene-Butadiene Rubber, Butyl, Ethylene, Propylene Rubber, Silicone, Polychloroprene, or Fluorocarbon.

Rubber is a great material for insulated cables. It has superior insulation in a wide range of temperatures, as well as being water resistant.

Rubber cables are especially useful in environments with a high risk of mechanical damage, like being used as trailing lead. They resist abrasion and weathering, so they can handle harsher environments.

Rubber cables are also constructed in a way to provide excellent resistance against oils and other corrosive and noncorrosive chemicals.

Other characteristics of our rubber insulated cables include:

  1. Outstanding flexibility
  2. Excellent electrical insulation properties
  3. Outstanding chemical stability;
  4. Satisfactorily physical and mechanical properties
  5. Durability and wear resistance;
  6. Oil resistance and flame retardancy
  7. 100 percent waterproof

Available Models

Independently, additives have little impact on the performance of these rubber base materials. However, by adding various additives, their performance can be changed significantly.

Typical rubber cable compounds include natural rubber, SBR or styrene-butadiene rubber, butyl, EPR or ethylene-propylene rubber, silicone, polychloroprene, chlorosulfonated polyethylene (PCP), and fluorocarbon.


Untel provides a wide range of insulated cables, including rubber and thermoplastic cables up to medium voltage. The insulated cable categories include:

PVC Cable Compounds

Certain disadvantages of PVC rubber in cables are that it is a high-dielectric material, has a high-induction loss, and can heat up. The maximum voltage an AC cable can allow is 10 kV.

Polyethylene – Moisture Cross-linkable Systems

Moisture cross-linkable polymer systems allow users to create a sticky mix that bonds polymers without the need for an “expensive” curing process. This process, which requires substantial energy, can be replaced with a low voltage polyolefin cable system which will include add-ons for specific customer needs.

EPR Moisture Cross-linkable Systems

EPR compounds offer high-temperature stability and superior electrical performance and compete well with other materials. However, the manufacturers need to invest in CV Lines to produce this material type.

Peroxide Cross-linkable EPR Compounds

Cross-linkable EPR compounds offer high-temperature stability and superior electrical performance. These types of compounds are reliant on the production of CV Lines for their cross-linking. Production on CV Lines is expensive, but it is possible to produce low and medium-voltage cables utilizing this material type.

Cross-linkable Polyolefin Compounds

Elastomeric polyolefin compounds have high temperatures, good electrical and mechanical properties, and thermal stability. These are used in products such as bags, belts and battery housings.

Thermoplastic LSZH, FR Jackets

These cables are made for use in enclosed locations with poor ventilation, such as tunnels or railways.

Bedding/Filler Compounds

In order to help maintain cable shape, reduce water ingress, and provide additional flame retardant benefits to the overall cable construction, halogen-free compounds are used for bedding and filler.

Untel also handles many other compound types, including some that are newly popular in the industry.

WINKA cables

WINKA offers a variety of insulated sockets and extension wire harnesses for off-shore and on-shore plants that are high quality and allow for their cables to operate in rough environments.

To ensure the safety and life of machinery, cables must be reliable in their own workings and withstand harsh environments. Safe, quality cables with resistant materials can ensure that you have daily reliability for machinery and equipment, as well as a lengthy lifespan for plants, equipment, platforms, vessels, and more.

One of the best features is that our cables can safeguard your home and industrial appliances from fire by eliminating excess heat.
