Porcelain stay insulator also called porcelain guy strain insulator / ceramic guy wire insulator is an insulator generally of elongated shape with two transverse holes or solts. Porcelain stay insulator can be designed in eight corners, four corners or egg/ walnut type. Porcelain stay insulator is used for it irreplaceable function for distribution power system and outstanding features. Stay insulator is designed in accordance with international standards.

Other porcelain stay insulators
Other porcelain stay insulators can be designed in egg / walnut insulator used on LV power lines.
