The U1-WP high current portable earthing device with co-operating DI-B insulating pole protects the workplace at line and station electrical equipment, equipped with flat bus-bars disconnected from the power source through the connection to the earth clamp. The set can be mounted on bars with dimensions: gauge up to 50 mm, defined width: 60, 80 or 100 mm. U1-WP device is produced one-phase version, it can be used for currents up to 60kA for time duration of short circuit tr = 1 s.
Earth clamps are used in all earthing device types. It is possible to purchase them individually, as spare parts. "Activation" indicates these clamps in a special way.
The P earthing device extension is designed for reliable connection of the earthing device with an earthing system not directly accessible in the earthing place of network, overhead and indoor electrical equipment of low, medium and high voltage in the circuits for different rated currents Ir. The highest one second rated current can not exceed 31.5 kA. The extension is an element of earthing system and fulfils the requirements of the PN-EN 61230:2011 (IEC 61230:2008) standard.
Phase clamps are used in all types of earthing devices. As a standard, we offer clamps for round bus bars for round conductors - WT-2, WT-2/B (for diameter up to 29 mm), or WT-3, WT-3/A, WT-3/B (for cross section 525 mm2), and for flat bus bars WT-P, WT-P/A or WT-2/A, WT-2/B. It is possible to purchase them individually as spare parts. "Activation" indicates these clamps in a special way.
The U portable earthing device protects the workplace at line and station electrical equipment, equipped with round conductors or flat bus-bars disconnected from the power source through the connection to the earth electrode.
The U-BG earthing device for power fuse bases is used for protecting workplaces at electrical power installations, equipped with E14, E18, E27 or E33 threaded fuse sockets, by connecting one side of the base to the earth (on the side of the thread for screwing in the fuse head). The screw cartridges work as line clamps.
The U-BM earthing device is used for protecting the workplace at electrical power installations equipped with BM type fuse bases, by connecting one side of a base (on the side of the device being earthed) with the earth electrode and at the same time electrical separation of the other side. U-BM earthing device is designed for rated currents Ir1 from 4 kA up to 9 kA and U-BM/00 for rated currents Ir1 from 4 kA up to 6.5 kA.
The U-LI10 portable earthing device is designed for earthing insulated lines equipped with bolttype terminal with diameter of 10 mm (e.g. made by “MALICO”). Maximum rated current Ir1 for rated time tr=1 second is Ir1= 4 kA. Permissible operating temperature is between -25oC and +55oC.
The U-LI11 portable earthing device is designed for earthing insulated lines equipped with bolttype terminal with diameter of 11 mm (e.g. of type TTD2 CC made by “SICAME”). Maximum rated current Ir1 for rated time tr=1 second is Ir1= 6.5 kA. Permissible operating temperature is between -25oC and +55oC.
The U-NN/A portable low voltage earthing devices are intended for earthing the conductors in circuits of overhead lines, for different rated currents Ir (the highest one second rated current shall not exceed Ir1 = 9 kA for U-NN/A). Permissible temperature of work is between -25oC and +55oC.
