DP20, DP40 Discharge Probes
- For discharging high voltage cables after testing
- Highly flexible, clear silicone covered earth cable
- For use with the PT18-10 and PT30-10 cable test sets
The DP20 and DP40 discharge probes are designed for discharging high voltage cables after testing. The probes are supplied as standard accessories for the T&R PT18-10 and PT30-10 cable test sets, and are also available separately. The discharge probes consist of a pointed probe connected to a 5m long earth lead via a series of surge resistors with an insulated handle. The earth lead insulation is clear silicone allowing the conductor to be easily inspected, and is terminated in an M6 hooked crimp.

Note: Under no circumstances must these discharge/earthing probes be connected to energised ac distribution systems.
