Cable Jointers Umbrellas

UMB 8HD is a non-conductive umbrella with no metal parts and an easily identifiable company logo – in the above photo this was Western Power Distribution, a UK DNO.

The Jointers Umbrella is compatible with an universal umbrella clamp (UMB4CLP) and unlike metal telescopic poles that stop working when dented the fibreglass poles are unaffected and continue to work.

The Jointers Umbrellas are available in blue, green, black and orange high vis whilst still allowing natural light through into the work area.

If there is a possibility of rain during cable jointing a tent must be erected, one end of which must be open to ensure good entry and exit and good ventilation for fumes. The cable joint position must be kept dry when jointing and splicing copper or fibre type LV MV and HV cables, including 11kV/33kV power cables. 

When jointing cables care must be taken by the Jointer not to char or burn any PVC material, such as cable sheath, as this will cause toxic gases to be given off. During the tinning or sweating operation care should be taken by the Jointer to avoid the inhalation of large volumes of the fumes emitted, and tent flaps should be raised to permit the flow of clean air through the jointers tent. At the same time the Jointer should position himself in such a way that the clean air flow carries the fumes away from his face.
