What Are The Flame-retardant Properties Of The Insulators?

In the process of power equipment manufacturing and power distribution system design, suspension composite insulator must maintain the material properties without being damaged under various extreme working conditions. Flame retardancy is a crucial parameter for evaluating composite suspension insulator the behavior of materials when exposed to heat sources or flames. Standards such as UL 94 are commonly used to classify and experimentally determine the combustion response of materials.

The influence of the composition of polymer suspension insulator material itself, additive formulation, and curing process on combustion behavior. Some insulating materials exhibit a short burning duration in the UL 94 V-0 rating test, meaning the material extinguishes rapidly after the flame is removed and is unlikely to continue burning at high temperatures.
