Cable glands can be designed to perform these functions:
3.7 ELECTRICAL CONNECTIONS
Connections between conductors and between conductors and otherelectrical equipment shall provide electrical continuity andadequatemechanical strength.
Ross - Courtney lug.
Terminating - crimp lugs.
Joining cables of the same size - crimp links.
When crimping it is important that the correct crimp type lug for the cable and the correct tool for that lug is used.

Blue point connectors (BP)
Bolted & clamp connectors
18.104.22.168 Soldered connections
Where a soldered connection is used the design shall take account ofcreep, mechanical stress and temperature rise under fault conditions.
Red Brown, dark Blue, Grey, White, any colour other than green/yellow, green, black, yellow or light blue
22.214.171.124 Preparation for connection
The insulation on a conductor shall not be removed any further than isnecessary to make the connection.
For connections between insulatedconductors the connection shall be insulated to provide a degree ofinsulation not inferior to that of the conductors.
Any damaged insulationshall be reinstated.
Electrical insulation tape
silicon masticInsulation of conductors
126.96.36.199 Mechanical stress
All cables and conductors shall be installed so that there is no unduemechanical stress on any connection.
188.8.131.52.1 Loosening of connections
Connections shall be made so that no loosening is likely because of vibration,alteration of materials or temperature variations towhich the connections
are likely to be subjected in normal service.
