Lightning protection system installation work, Electrolux factory construction project, Rayong Province

Lightning rod, LIVA brand, model LAP-DX-250, installed on the roof, 6 meter high pole, pulling 1 layer of rope.

Bare copper grounding cable, size 95 sq.mm., threaded in 1” UPVC pipe with grounding system.

 Assembling the lightning rod head

  Use a fishtail with a cable cover. Connect to the connector before threading the galvanized pipe.

Four-sided clamping sling Keep it waterproof. Work under the roof is fixed to the frame under the roof for strength and good wind resistance. Use a stainless steel cone to cover the base of the pole with waterproofing. No more worries about water leaks.

Cable number 95 Sq.mm threaded in UPVC pipe 1"

Ground system

The area is mountainous and mostly rocky. and the soil is filled in, causing the ground value to be higher than the standard. But with more than 18 years of experience

The team was able to achieve a ground value that was within standard criteria. The value was 2.10 ohms (Ohm), which was satisfactory.

The equipment uses a 5/8" copper-plated ground rod connected to a wire number 95 Sq.mm because there is little ground space. Use the method of making a spreading ground (Star)

Recommendations for lightning protection system work

 The resistance of the grounding system should be checked every year to ensure that the resistance is within the standard, not exceeding 5 ohms.

     and not more than 20 % of the first test measurement of the grounding system installation in the following year.

Check the wiring system and equipment completely to ensure that the system works efficiently. annually
