The specification of the correct cable for the electrodes is essential for the long term performance of the electrodes. The cable insulation must be capable of withstanding the environmental conditions in which the electrodes are placed and also the conditions experienced during construction. The determining factor for the durability and function of the electrodes is often the cable insulation.

We supply three types of stock cable as standard options with our electrodes

• 1.5 mm² high performance double insulated blue cable manufactured by Raychem part no. 44A0111.This is used for the LD10 reference electrodes which require a smaller cable.
• 2.5 mm² blue XLPE/PVC stranded copper cable. This is the cable most widely used for electrodes embedded in concrete providing good durability against physical and chemical attack.
• Rubber sheathed cable supplied by Lapp Cables product No. H07RN-F. These tough flexible rubber sheathed cables are ideal for wet conditions and are used for the portable LD200W reference electrode and the LD250 combined electrode for soil applications.

We can supply the electrodes with other cable specifications such as XLPE/XLPE, PVC/PVC and HMWPE but these will be special orders and may be delayed while the cable is manufactured.

As an alternative we are able to supply the silver/silver chloride electrodes without cables attached but calibrated and ready for cable attachment using push fit connectors. Click here for the instructions for cable attachment.
