Shielding kits of Ep-4(L) type

Shielding kits of Ep-4(L) type are intended for live working at non-deactivated HVL at voltage 110-1150 kV inclusively as well as for live working at earth potential (pillars and cross-arms) during cold season.

Kits provide protection against impact of:

*       electric field including constant critical tension of a wire surface;

*       any displacement current of any magnitude of voltage;

*       pulse current under electrical contact loss of shielding kit with line wire;

*       air ions especially heavy ones (aerosols) inhalation of which is inadmissible;

*       electromagnetic field produced by corona discharge.

Shielding kits of Ep-4(L) type are completed with elements galvanically bonded to each other:

*       Insulated shielding jacket with hood;

*       Insulated shielding jumpsuit;

*       shielding helmet cover;

*       face shield with fastening to helmet;

*       shielding knitted gloves;

*       leather made shielding boots or cold-protective shielding boots.

The kit is certified by the State Standardization Organization (Gosstandard) and State Sanitary-and-Epidemiologic Institution of the Russian Federation.
