In combination with the conductor covers, the suspension string and pole head cover is used to allow :
• The operator to reduce the distance between his working area and the parts protected by the cover.
• It can also be used to avoid accidental contact between phase-to-phase and phase-to-earth.
In all cases, protruding network elements must be removed before the cover is fitted.
If the conductor is held by a conductor support stick or sticks, the suspension clamp must also be removed.
• Model 1: chimney integral with the cover for insulators with a diameter of 175 to 200 mm / 7’’ to 8’’.
• Model 2: removable chimney. 4 chimneys of different dimensions can be adapted to all MV insulators.

The chimeneys are fixed in place by 6 polyamide bolts and washers.
The door model 1 can only be used to protect the head of a conductor support stick.
The door model 2 can be used :
• Protect the head of a conductor support stick.
