The Hepworth range of temporary continuity connectors has been developed over many years in co-operation with the United Kingdom electrical distribution industry. The connectors are designed to afford protection to personnel by maintaining electrical continuity across breaks in metallic armour and sheathing during jointing or repair operations on underground distribution cables.

They consist of cross bonds of flexible tinned copper braid which are connected to the armour or sheath by special clamps. The braid has a primary insulation of clear polythene tubing and certain connector designs have an adjustable secondary insulation in the form of a sliding outer sleeve.

The range of connectors covers the requirements of a wide variety of joint configurations, and the necessary cross-sectional area of the bond to meet anticipated fault levels is achieved by means of permutations of tinned copper braids, the basic product having a cross-sectional area of 22mmÇ (2 x 11mmÇ CSA).

Please note that the above product range has been successfully tested to a short circuit withstand of 6KA @ 1 SEC (Test Certificate N°: T04/261/GH)
