Post insulators are designed for insulating and fastening of conductive parts in electric equipment, distributive devices of power stations and substations. Post in-sulators are used to complete: disconnectors of indoor installations, circuit-breakers, power junction boxes and fuses. These insulators are also used for busline insulation. The insulating part is made of ceramic electrotechnical material of subgroup of 110 ГОСТ 20419-83. Post insulators conform to ТУ 16-528.105-77 standard.

Reinforced stick-support insulators are designed for outdoor operation as well as for distributive devices of power stations and substations. Stick and stick-support insulators supplied by the company are designed for operation within 1 up to 110 kV voltage band and within 1,0 up to 20,0 kN load range. These insulators meet ГОСТ 9984-85 standards. The insulating part is made of ceramic electrotechnical material of subgroup of 110, 130 ГОСТ 20419-83.

Bushing insulators are designed for distributive devices operating both indoor and outdoor. These insula-tors are designed for insulation and installation of conductive parts of indoor and outdoor switchgears of power stations and substations, switchgear and control gear. These insulators are also used for connection with outdoor switchgears of AC powerlines (6 up to 35 kV, up to 100 GHz). Insulators are reinforced by iron cast or aluminum alloy flanges fixed with Portland cement.Bus bars are made of aluminum.

Line porcelain pin insulators are designed for insulating and fastenening of wires on overhead AC/DC transmission lines (voltage up to 1000V, frequency up to 100 Hz) as well as communication lines. Made in conformity with ДСТУ 3546-97 (ГОСТ 30531-97). The insulating part is made of ceramic electrotechnical material of subgroup of 110 ГОСТ 20419-83.

Covers for oil- and gas-filled lead-ins. Non-reinforced covers. These covers are designed for external insulation of lead-ins and protect the major insulation from weather impact serving also as a reservoir for oil or gas which fills the lead-in. These covers meet the standards of ОСТ5862-79. Insulating part is made of ceramic electro technical material of subgroup of 110 ГОСТ 20419-83.

Covers for coupling capacitors, current and voltage transformers.  Non-reinforced ceramic covers. These covers are designed for outdoor operation of coupling, power takeoff and voltage divider capacitors on AC or DC high voltage power lines and provide both reliable operation of high voltage power lines and power system stability. These covers are designed for 35 up to 1150 kV current transformers. These covers operate outdoor, serve as an external insulation and protect transformers inside parts from weather and mechanical im-pacts. Made in conformity with ГОСТ 5862-79 standards. Insulating part is made of ceramic electrotechnical material of subgroup of 110 ГОСТ 20419-83.

Covers for air circuit-breakers. These covers are designed to complete air circuit-breakers. Air circuit-breakers provide reliable operation of high voltage power lines as well as stability of power systems. The covers conform to ГОСТ 5862-79. Insulating part is made of the ceramic electrotechnical material of subgroup of 110 ГОСТ 20419-83.

Porcelain covers for electric filters

Porcelain covers for different purposes. In total range of insulators delivered by SZVI the hollow apparatus porcelains are the most principal items designed for production of low-oil, SF6 and air breakers, current transformers, high voltage bush-ings and arrestors.
