Silicone rubber features outstanding electrical insulation and weather resistance, with a volume resistivity exceeding 10¹⁴ Ω·cm. It is UV-resistant, ozone-resistant, and does not age during prolonged outdoor use. It is flexible and easy to install, fitting snugly around wire joints. Thanks to these characteristics, it is widely used to make insulating protective covers for overhead power lines, commonly known as "little red caps," effectively preventing short circuits and electric shock hazards caused by exposed joints, serving as a vital protective material for the safe operation of power distribution networks.
