Why Are Pa66 Insulation Components Used As Flame-retardant Materials For Cable Terminals?

The thermal and combustion behavior of material Aluminum Cable Lug is a key factor. PA66, a type of nylon 66, has a melting point of 265°C and, after flame-retardant modification, meets the UL94V0 standard. This means that in a vertical burning test, it extinguishes itself within 10 seconds after the flame is removed and does not produce dripping burning particles.

In practical applications of Compression Cable Lug, cable lugs is often in an environment with frequent plugging and unplugging, large contact current, and the possibility of local heating or electric arc. Using ordinary plastic materials would increase the risk of thermal expansion or fire spread. Selecting PA66 insulation components, achieving a V0 flame retardant rating, means that the material can quickly self-extinguish in the event of an accident, reducing flame spread and the release of toxic fumes, thus providing a higher level of safety for the overall system.
