Permali Stay Wire Insulators Supplier

Permali Stay Wire Insulators are manufactured from a specially assembled impregnated laminated wood beam and supplied complete with all the necessary metalwork. Permali Stay Wire Insulators comply with BS 1320: 1946, the overhead line regulations ELC 53: 1947 and ESI 43-91: 1977. The greater strength of Permali, compared with natural timber, allows for a considerable reduction in cross section and they are not subject to any of the defects of natural timber insulators (such as variability, splitting, weathering and moisture absorption). Tests have shown that impulse flashover along the surface of a Permali insulator, whether new or old, leaves no trace and has no effect on the insulator.
