∆
Minimise strain on the HVSC Plus downconductor
∆
The HVSC Plus downconductor may be installed internally or externally on the structure
∆
The HVSC Plus downconductor should be installed as close (flush) as possible to the
structure
∆
Minimise the number of bends and use the most direct route to ground
∆
Re-entrant loops ("doubling back") of the HVSC Plus downconductor MUST be avoided
∆
Ensure minimum bend radius is not surpassed, i.e., smallest bend radius allowed is 430 mm
(20")
∆
Parallel routing with other services should be avoided. If unavoidable, the minimum
separation distance is 2 metres (Figure 9)
∆
If the HVSC Plus downconductor has to cross other services, ensure it crosses at right
angles. Use a conduit that extends at least 1 m beyond either side of the existing service
