What are the benefits of rubber insulated cables?

Rubber Cables are utilized in a wide range of applications. They come in single and multi core varieties and are used for trailing and flexible supply lines. Even at subzero temperatures, they will remain flexible. These wires, despite their high cost, have a benefit. Rubber cable maintains strong electrical performance in both a high-temperature and low-temperature environment. Rubber cable can maintain good electrical energy in both hot and cold weather.

A flexible cable is generally exposed to the smallest bend radius where it has to deal with a fixed end connection. For example, if you have your phone charging and it gets knocked off the counter, the kink in the cable is typically going to be right as it exits one of the plugs. These kinks tend to cause microscopic (and sometimes macroscopic) damage to the insulation and the glue that holds everything together. Over time, this damage addes up and you end up with a torn insulator. To deal with this, companies will put strain reliefs at the plugs to reduce help reinforce the cable, but this doesn't always totally mitigate the problem.

You can see that companies like Apple are trying to lengthen the strain relief on their plugs to reduce this problem - without having significant impact on the aesthetic design.

flexibility and water resistance are two major benefits of rubber insulation though the flexibility is greatly affected by temperature and type of rubber. Silicone rubber is best in cold climates.

You mean silicone rubber insulated cables?

They are rated for up to 180 degrees Celsius.

This is one of the most common and dangerous misconceptions about electricity.

My boss told me use these gloves to work with electricity that had a rubber coating and I took my meter out and checked resistence across the rubber in front of him. Many rubber gloves are conductive enough that they spread it across your hand and are therefore way more dangerous than touching wires bare handed, blue nitrile gloves are worse than the one I'm remembering. On top of that you might feel safer which makes you yet more endangered

Rubber can have all kinds of stuff in it and some of that is conductive. Never trust a material witj electricity unless you know exactly how conductive it is.

Asking about rubber is simply asking about an unknown substance

Why do most appliances used at home have rubber insulation? While rubber is a good electrical insulator, it is very rarely used in wire insulation today. Most wire insulation in use is a thermoset plastic insulation made with plastic similar to vinyl or polyvinyl chloride, but with more flexibility and abrasion resistance. The home appliance industry has to meet safety standards applicable to their products in the country they are marketed in, and rubber’s low melting point and lack of resistance to oils and solvents, along with the fact it does dry out and crack over a period of time mean it isn’t the best (or cheapest, always a factor) insulation for appliance electrical wires.

This may sound like it is splitting hairs, but there is a difference between rubber, generally a material made from natural products, and thermoset plastics. For a more general answer, appliances used in homes have to be safe to use, and electricity, especially in the presence of water, is extremely dangerous.

The rubber insulated cable types are different,but they have the following features.

  • All rubber cables over other insulated cables is the excellent flexibility in temperature range
  • Very good water absorption properties
  • Superior abrasion resistance and weathering resistance
  • Oil resistant according to EN 60811-2-1
  • Excellent resistant to oils and other chemicals
  • UV, sunlight, ozone, oil, resistant
  • For fixed installation lowest temperature is -40 °C.
  • Rubber Insulated Cable Temperature range _25°C to 60°C.
