CHC31 Intermediate earthing stick for connections at great height, max Isc 31,5 kA/1s

STANDARD(S) : IEC 61230

USE :
Intermediate sticks for connections at heights are used to relieve the operator by bringing the earthing point 3 or 4 metres lower, which facilitates the various operations:
• checking for the absence of the nominal voltage,
• placing and clamping the aluminium stick on the conductor using the insulating stick,
• releasing the operating stick,
• placing the flexible earthing device between the earthing point and the earth bar,
• repeating the operation for each phase,
• carrying out the same operation in reverse order for removal.

The CHC31 conductor pole must be installed using:
• either specific CHI31 type dedicated insulating stick
• or an RTTE type insulating stick equipped with an ERTTECH end fitting

These sticks are made of IEC 60855 type foam-filled tubes, colour orange.
It is strongly recommended that they be checked regularly.

SPECIFICATIONS :
Aluminium tube Ø 31/35, cross-section 207 mm², with a special light alloy contact clamp with an
elastic conductor clamping system fitted at the top.
• Clamping ranges Ø 10 to 60 mm, Ø 20 to 120 mm, Ø 70 to 120 mm or 120 to 220 mm (depending on head type).
• The electrical contact between the line clamp and the conductor stick is made directly between the clamp and the aluminium tube as well as by 2 tin-plated copper flexible braids.
The clamp is tightened on the conductor using the lower insulated section, with the male end fitting engaged in the female end fitting.
• The bottom of the Ø 35 tube includes two Ø 30 aluminium earth studs designed to take earth clamps, type S540, S1560 for example.
