GUIDE IN SELECTION OF POWER CABLE JOINTS AND TERMINATION

When making a decision as to the best choice of devices to purchase, here are some of the questions and opportunities that should be considered:

Are the components of the device compatible with the cable being spliced or terminated?

Did the device pass all the tests that were specified so that it meets the requirements of the electrical system involved?

Are codes applicable in the decision to use the chosen device? Review all safety requirements involved in the construction, application, and installation of the device.

Will the device meet the mechanical requirements of the installation?

Can the device be assembled with the tooling that is already available or are special tools required?
Consider the positioning of the device.

Splices are not recommended for installation at bends in the cable. Terminations are normally installed in an upright position. Other positions are possible but require special attention.

Environmental conditions are of importance to attain expected life of any device.

Heat may affect the ampacity of the device.

Cold may have an effect on the assembly during installation. Contaminants are critical to the leakage path of a termination.

Moisture is always the enemy of an underground system and must be controlled in construction and installation.

Are there any existing work practices or procedures that will conflict with the application of this device?
Investigate the economics of using different devices such as emergency reserve parts, training new personnel after original installation personnel have gone.

The cost of the device and the cost of installation.

Will the device do the job as well or better than what is presently used?
