Insulating Poles for High Voltage Detectors MV HV 11kV 33kV 66kV 132kV

Insulating Poles for High Voltage Detectors MV HV 11kV 33kV 66kV 132kV
Pfisterer offer a wide range of insulating poles suitable for high voltage detectors with different HV applications including rail power systems.
Insulating poles are hand-held devices for the operations and testing of live components with nominal voltages of 11kV, 33kV, 66kV and up to 132kV.
The insulating poles are compatible for us with all KP-Test 5 Series allowing all voltage detectors to be optimised for particular applications on the system.
The insulated poles are used by personnel carrying out live operations such as HV high voltage drop-out fuse replacement, live-line tapping at earthed locations or ABSD switching on earth poles.

Insulating Pole Extensions for Voltage Detectors
This insulating pole extension makes it simple to extend the Pfisterer insulating poles of voltage detectors. The insulating pole extension is screwed onto the existing insulating pole. This does not reduce the minimum insulation length.
These insulation pole extensions can be used for:
- KP-Test 5
- KP-Test 5 dual
- KP-Test 5L
- KP-Test 5L dual

In-service Tests for Voltage Detectors
Depending on national regulations in the country concerned, in-service tests are required for voltage detectors with nominal voltages above 1 kV. Pfisterer have been successfully carrying out these in-service tests on their own test equipment for many years. The voltage detectors are tested according to the specifications and immediately adjusted if necessary.
