Description de Produit
HV porcelain pin insulator of SHF20G1 type
There are three modifications of the insulator after the manner of its coupling:
with the polyethylene capsule, with the composite material thread corresponding to the requirements of SFS (Finland) standard and BS (Great Britain) – a small head.
Insulator meet TU 3493-170-00111120-2000 requirements.
