Benefits of technology

This new type of wire or cable made from an alkaline-resistant plastic contains fewer chemicals than traditional materials that are commonly found on rails for use during construction projects. It also doesn't emit any dangerous gases like chloride gas when exposed to water over time without losing its effectiveness due to it being more resistant to fire damage compared with other types of conductors such as copper.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the properties of insulated wires made from silicon rubbers that can resist fires without causing damage or contamination during use.
