Description

SPECIFICATIONS

 PSS-120B suspension glass insulators

are used on HVDC transmission lines with a voltage of 35-220 kV, with loads not exceeding normalized 120 kN. Insulators insulation parts have a special shape. Spherical shape allows insulator to work better in desert, steppe and open spaces under a high wind load due to better self-cleaning of the insulator.

Insulator type Mechanical breaking force,

PSS-210B suspension glass insulators

are used on HVDC transmission lines with a voltage of 220-500 kV, with loads not exceeding normalized 210 kN. Insulators insulation parts have a special shape. Spherical shape allows insulator to work better in desert, steppe and open spaces under a high wind load due to better self-cleaning of the insulator.

PSK-300A suspension glass insulators

are used on high-voltage transmission lines with a voltage of 500-1150 kV, with loads not exceeding normalized 300 kN. Insulators insulation parts have a special shape. Conical shape allows insulator to work better in desert and steppe under a high wind load due to better self-cleaning of the insulator. Insulators were designed for the 1150 kV HVDC Ekibastuz–Centre transmission line
