Temporary continuity connectors for Metallic Cable Armour or Sheathing.
Developed over many years in co-operation with the industry. These connectors are designed to offer 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 clear polythene tubing insulation and certain connector designs have an adjustable secondary insulation in the form of a sliding outer sleeve.
The range covers 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 22mm² (2 x 11mm² CSA).
Successfully tested to a short circuit withstand of 6KA @ 1 SEC (Test Certificate available on request).
Specialised connectors can be made to order, and lengths varied to suit individual requirements.
Temporary continuity connectors are designed to meet the basic requirements for cross bonding pipe diameters or combinations of diameters within the normal service range.
Custom units can be manufactured to network specifications on request. Please contact us for further information.
