Safe overhead line operation
November 2007
Enclosures, Cabling & Connectors
The Snap-On Clamp, locally designed and manufactured by Surgetek, is designed to withstand electrical fault current conditions or for equipotential bonding of electrical components when linesmen are standing on ladders and working on overhead line networks. Tested to IEC 61230 (SANS 61230), the Snap-On Clamp devices are for use with conductors from 4 mm to 25 mm in diameter.
Of particular importance is that the Snap-On Clamp and Earth Clamps are conditioned in a climate chamber according to IEC 60068-2-11 for ageing purposes. The Earth Clamps are easily connected to a cluster bar and the Snap-On Phase Clamps are simply applied and removed with the aid of a two-clamp dispenser.
All terminations lock positively onto the snap-on phase clamps, and universal type screw clamps prevent accidental loosening of the terminations. All terminations are sealed to prevent humidity penetration into the cable.
