Grounding device ZPL are intended for worker's protection from electric shock on the de-energizing parts of high voltage lines in the case of mistaken voltage feed to this part or appearance of induced voltage. The main parameters of grounding devices: Name of parameter Marking of grounding device ZPL-1B1, 1 ZPL-10B10, 10 ZPL-35-1 ZPL-35-3 ZPL-110-1 ZPL-110-3 ZPL-220-1 ZPL-220-3 ZPL-330-1 Nominal voltage of electric installation, kV 1 10 35 35 110 110 220 220 330 Length of grounding conductor, m, not less 9,0 10,0 12,0 12,0 12,0 12,0 15,0 15,0 12,0 Length of each short-circuiting conductor, m, not less 0,9 1,6 - 4,5 - 6,0 - 9,0 - Quantity of clamps, p 5 3 1 3 1 3 1 3 1 Quantity of insulating rods, p 5 3 1 3 1 3 1 3 1 Section of conductor, mm 2 , not less 16 25 25 25 25 25 25 25 25 Mass, kg, not more 5,0 6,0 6,0 11,0 7,0 11,0 8,0 15,0 10,0 Portable grounding device are manufactured for high voltage lines 0,4 kV with five rods; for high voltage lines 10 kV with three rods with spring, bayonet or screw clamps. Collector phase clamps are manufactured as a unit with insulating grounding rods. According to customer's parts lists circuit design of connection of phase clamps can be represented as wave or star. In grounding devices for power lines 35 kV and more screw C-formed clamps are used. The clamps are connected with insulating rods by means of butting block with screw compression. Portable devices for 35 kV and more can be supplied in single-phase and three-phase design. For grounding to earth the set of supply can include (according to separate demand) temporary grounding pin. Portable grounding device for air synthetic wear resistant cloth or (according to separate demand) wood boxes for ensuring long exploitation life.
