Medium Voltage Termination – Observations
Indoor 3 Core XLPE Termination Installed Using Alternative Improved Clearance
Dimensions
Picture 1 shows the termination in varying stages of completion. Please note: The installation instruction provided
with each kit details both the standard cable preparation details and the dimensions for the improved clearance
option.
Observations
1. Shows the application of the mastic melt tape to the
bushing and to the metalwork. This not only ensures
an additional moisture seal but improves impulse
voltage withstand levels from 75 to 95kV.
2. Shows the application of the red anti-track sealant
tape over the lug barrel.
3. Shows the position of the stress control tube which
in this example has been fitted in a higher position
up the core with the following additional benefits:
a. Improved clearance dimensions between phases
at the top of stress control tubes, which also
gives the user the ability to core cross whilst still
retaining the required clearances.
b. Not only does it save the installer time because
less screen material is removed, it makes it far
easier to use screen removal tools in between
the cores.
c. It is easier to use a gas torch between the cores
at a higher point, resulting in the increased
likelihood that even shrinkage of both stress
control and anti-track tube is achieved at the
end of the screen point.
4. Shows the installation of the right angle bushing
protection boot. A shorter skirt version is also
available for short bushings.
