VELOX CABLE JOINT – DRY
Is used to connect two cables without use of shrinking tube or filling compound.
The cable joint is a dry joint and very easy to use.
The cable joint is provided with 2 glands PG29, IP65. max. cable diameter: depending on gland used.
This joint can be used for any cable up to a max. diameter of the size a 40mm gland can take. If required smaller glands can be supplied together with reducer from 40mm.

- These instructions are relevant for a range of different Low Voltage straight and branch joints. They show typical arrangements but the procedures are the same for any variation of joint.
- Instructions assume that cables are de-energised.
- Instructions are for guidance only, and subject to standard jointing procedures which should always be followed.
- Dispose of all waste materials and packaging safely, clear accidental spillage immediately.
- Do not use in a confined, unventilated area, avoid breathing the resin curing vapours.
- Wear protective gloves provided at all times when handling cold pour resins.
- Avoid contact with skin and eyes. In case of accidental contact treat the area with copious quantities of water. Full health & safety information is available upon request.

Jointing the cables
Clean and decrease the armours and lead sheath (if present) and abrade the outer sheath from the armours to a distance of 10mm outside the joint case. When jointing the cables use the connectors provided or other approved types. For power cables use phase separators (if supplied) in the vicinity of the connectors and in any event ensure at least 10mm separation between connectors. A typical connection for a branch joint is shown below using mechanical connectors.
Remove the insulation from each end of the earth strap as shown. Attach the braid to the main cable armours using constant force spring 1. When attaching the ends of the braid allow the braid to extend beyond the spring and after applying one full turn fold the braid back over the spring, 2, as shown. Cut off any excess. For straight joints simply use spring 1 on each side of the joint.
Apply the braid as shown using the smaller springs on the lead. Fold either end of the braid back on itself as shown in the drawing above and cut off any excess. If a branch cable is present connect the braid to this cable as described above.
Completing the joint
After making the earth braid connections place a half of the joint case around the joint positioning centrally. Cut the ends of the case to suit the cables using a hacksaw. Make sure that the connectors are at least 10 mm apart.
Use PVC tape at the cable entry points to seal the joint case. Mix the resin as instructed on the resin pack and pour into the joint case until the case is completely full. Finally fit the lid to the filler hole.
Ensure cable joint is level and both cables and joint are supported independently.
For applications up to 1000 Volts, the joints may be filled under load conditions. The completed joint should be left uncovered before back-filling for two hours to allow the resin to fully cure. Ensure that there is no movement of the cable cores during curing of the resin.
