Lightning Protection System & Grounding
Omazaki Design & Build is also a design consultant and contractor for lightning protection systems and grounding projects in Indonesia. As a contractor, we design, present and install external and internal lightning protection systems, both active and passive, conventional protection (such as Franklin and Faraday cage) or modern lightning protection systems such as radius, electrostatic and even radioactive types, for the industrial sector, buildings such as buildings high-rise buildings, hospitals, or for sports fields such as golf courses or driving range, as well as appropriate earthing systems. The level of our service is highly dependent on the level of risk of lightning strikes as well as the Occupational Safety and Health (OSH) policy implemented by the client. Consultants and contractors services can be services in the form of installation of simple lightning protection system with uncomplicated technical considerations, or it can even be a large project that requires a site survey, evaluation, assessment, review, and/or in-depth study first. Our location in BSD, Tangerang Selatan, Banten province.
