TWO-POLE STRAIN CARRIER
The Two-pole Strain Carrier (RC401-2174 to RC401-2179 series) relieves the mechanical strain of the insulator string so it can be removed from the energized line for to be changed, either in single or multi-insulator string according to the string arrangement hardware.
Strain Poles are used with adjustable pole clamps and yokes, with trunnions and strain jacks.
Through the adjustable pole clamp the energized side suspension or anchor yokes are coupled to the Strain Poles. The pole clamps can be adjusted manually or with a Hot Stick.
The energized side yoke includes a steel hook.
The yokes are constructed of rolled aluminum sheets and include a hook string for anchoring to the structure.
The rated working capacity is: 6804 daN (15000 lb).
