- Using NFC 17-102 standards IEC 21186-96 France or to calculate combined with ISO 9385-2012 standards of Vietnam.
- Using early streamer emission lightning collecting needle H = 5m, RBV = 79m, protection protection level I, the needle is mounted on hot dip galvanized steel cylinder 114-? 60, high of 18m.
- use copper wires Cu / PVC 70mm² to connect the lightning collecting needle check box next to the address, the check box to the ground rods used bare copper wire 70mm².
- the connection between lightning collecting wires and ground rods welded using thermochemical methods.
- the earthing resistors lightning protection must not be greater than 10om.
- After construction is complete to check measurements, if not? ạt must take measures to handle (drilling additional wells or using chemicals to reduce ground resistance ...)
