Описание
PSttbe-1 heat-shrink sleeve is designed for connection of aluminum or copper conductors of cables with plastic, rubber and polyethylene insulation with armor or shield for voltage 1 kV: AVBbShv-1, VBbShv-1, AVVB-1, AVVBG-1, VVB-1, VVBG-1, APvBbShv-1, PvBbShv-1, VVGE, AVVGE, PvVGE, APvVGE, their equivalents and versions. The sleeves can be installed under ground (directly in the ground, in tunnels and channels) and outdoors (on trestles, cable trays, etc).
Преимущества
- Two types of protection against overloads and short circuit.
- Complete set of supplementary devices with the possibility of simple independent installation:
- – State contact KS47;
- – State contact KSV47;
- – Undervoltage trip RMM47;
- – Low-voltage release RN47.
- Improved arc suppression system: extended service life, increased resistance to short-circuit currents.
- Contact position indicator.
- Wide operating temperature range from –40 to +50° С.
- Simultaneous connection by FORK bar and flexible conductor is possible for power supply distribution via upper terminals, as well as connection by PIN bar.
- New ergonomic design of ON/OFF lever.
- Notched terminal clamps reduce the heat loss and increase mechanical stability of the connection.
