Usage Instructions Place SK Earth in a container that is easy to mix, and add water while stirring (approximately 7 to 8 liters of water is recommended). After thoroughly mixing, pour it into the grounding electrode (make sure to pour it in a way that surrounds the grounding electrode). Do not wait for it to harden; backfill immediately. As a finishing touch, sprinkling water on top of the soil and compacting it will yield even better results.

This terminal box is a grounding terminal box for electrical equipment. Please note that the crimp terminals for connections are not included as their sizes vary depending on the application. 【Features】 ○ Available in hard plastic (screw-mounted, plate type) and steel (with key, single-opening type). ● For other functions and details, please contact us.

• Lightning protection

This indicates the date, location, type, grounding resistance value, etc., of the buried grounding electrode. In addition to standard products, there are options for general grounding, lightning protection equipment, and tank trucks. 【Features】 ○ Available in brass and stainless steel materials. ● For other functions and details, please contact us.

• Lightning protection

Please install the terminal box in a location that can be easily inspected. There are various types of terminal boxes, handholes, and concrete foundations for terminal boxes (with display boards). 【Features】 ○ Materials include rigid vinyl, brass, and stainless steel. ● For other functions and details, please contact us.

• Lightning protection

The support pipe mounting platform is classified based on the shape of the building, installation location, roofing materials, etc. ○ For floor use (flat roof), gable roof, single slope roof, corrugated roof, tank use, and tile roof. Installation method: ○ For floor mounting platforms, a foundation is established on the flat roof, anchor bolts are inserted into the foundation, and the mounting platform is secured with those bolts. Since the wind pressure noise of the support pipe may resonate with the building, please install it on top of the beams. ○ The installation method for single slope and corrugated roof mounting platforms will vary according to the shape of the roof, using bolts, washers, spring washers, nuts, etc. However, if the roof is slate, ensure that the load does not directly affect the roof. Special care should be taken regarding waterproofing during installation. ● For other functions and details, please contact us.
