The surge protection device connector (SPD IPC) is designed to protect low voltage overhead lines and electric equipment against over-voltages. It enables the current from the lightning to be led to the ground.
The surge protection device connector includes the following elements:
- An insulation piercing connector,
- A terminal outlet inserted in the end cap of the connector,
- A surge protection device (metal oxide overmoulded with silicone) screwed into the terminal outlet,
- An earth system tail welded to the surge protection device.
The surge protection device reacts:
- After a certain number of overvoltages, when the current passing through the surge protection device increases by more than 1mA,
- In the case of atmospheric discharge (lightning strike), the current exceeding 65mA.
After the surge protection device has performed, the earth system tail physically separates from the connector. The surge protection device then should be replaced with an available spare part (comprising the surge protection device and the earth system tail).
These low voltage fuses cartridges NH00, NH1 or NH2 are type gG. They are used as protection unit of the low voltage public electricity supply networks and works. It is installed in: - Low voltage switchboards of the public electricity supply substations, - Cutout boxes, inside or outside supply switches, - Switch cabinets for subsurface networks, - Metering boxes and cabinets for different uses
This tape is designed to conduct the electricty into the earth system and to guarantee the default current runoff. If the copper gives an important electrical and the tinned coating protects from theft thanks to the non visible copper coating conductivity. The copper bonded steel offers a good economical alternative to copper. Furthermore Galvanized steel is an economical solution to coppered tinned steel and protect from the theft too. It has a good conductivity.
