4.4 Wiring

safety

¾

The signal line must be kept away from HV equipment or HV cable at least 50m.

¾

Try to wiring outdoor along the route under the eaves.

¾

At open space, the wiring must be buried with closed steel pipe; the steel pipe should

be earthed at one point, strictly forbid to use the aerial wiring.

¾

At high thunderstorm area or high induction voltage zone (such as HV substation),

the protective measures such as adding of additional high power lightning-proof

device and lightning arrestor etc must be used.

¾

The outdoor devices and circuit lightning-proof and earthing design must be

combined with the lightning-proof requirements for buildings, and comply with the

relevant national and professional standards.

¾

The system must be equipotentially earthed. The earthing device must comply with

both system anti-interference and electrical safety requirements, and not short-circuit

or mixed with zero line of strong current grid. When the system is individually

earthed, its earthing impedance should be not more than 4Ω, with the section area of

earthing conductor not more than 25mm
