The ShS10-12.5-SS-IV pin-type glass insulators are designed for securing and insulating uninsulated and insulated conductors of the SIP-3 type on overhead power lines and in distribution devices of power plants and substations of alternating current with voltages up to 10 kV inclusive and frequencies up to 100 Hz, operating in ambient temperatures ranging from -60 to +50 °C. The conductor can be fixed in the groove or on the neck of the insulator. The insulators are mounted on crossarm pins using polyethylene caps of type "K" or "KP". They are manufactured according to TU 3493-010-99267582-2015 and comply with GOST 1232-2017.
