Full-wrapped ceramic bushing insulators of the PTH 1.0 and 6.0 kV series

Description

Izolatory przepustowe ceramiczne pełnookute serii PTH 1,0 i 6,0 kV
Izolatory przepustowe ceramiczne pełnookute serii PTH 1,0 i 6,0 kV

Full-wrapped ceramic bushing insulators type PTH from PHPU “Izol-Plast” Sp. z o. o. are manufactured as a spare part for the renovated and repaired flameproof transformer stations type IT3S … and the series of types of flameproof transformer stations type MAR -….., built in insulation class H and C. 

Insulators from series PTH are built in a fully-wrapped version, i.e. the insulator includes:

  • 1kV or 6kV insulator porcelain, suitable for the type of insulator,
  • pin suitable for the type of insulator,
  • metal washers and nuts,
  • metal flange with a flameproof surface
  • sealing mass and filling-sealing mass.
