IS/IEC 62305 Lightning Protection Design: A Practical Guide for Indian Projects
How to run a risk assessment, pick a protection level, and translate rolling sphere radius into a buildable air termination layout.

DFMHUB manufactures, designs, installs and tests complete lightning protection and earthing systems for data centres, pharma plants, high-rise towers and manufacturing facilities across India.
Most lightning protection failures in India come from split responsibility — one party designs, another supplies, a third installs. DFMHUB owns the whole chain.
Quantified risk study that fixes the protection level before a single component is priced.
Air termination modelled on your actual roof geometry, not a generic rod-count rule of thumb.
ARK Make components produced and type-tested to IEC 62561 with batch traceability.
Trained crews for facade, roof and foundation work, with height-safety compliance.
Fall-of-potential earth resistance and continuity records for every electrode and test link.
Type 1, 2 and 3 SPD staging so transients never reach sensitive equipment.

Air terminations, mesh and down conductors, test links, bonding and coordinated SPDs, designed by rolling sphere method to the protection level your risk assessment demands.

Foundation rebar bonding, copper bonded and chemical electrodes, earth bars and enhancement compound sized from a Wenner soil resistivity survey to IS 3043:2018.
Risk assessment, physical damage protection, and protection of electrical & electronic systems.
Indian code of practice for earthing — electrode sizing, resistance limits and soil resistivity method.
Type-testing of LPS components: connections, conductors, electrodes, enhancing compounds and test links.
National Building Code requirements for lightning protection of buildings in India.
Selection and coordination of surge protective devices for low-voltage systems.
International practice for LPS installation and early streamer emission terminals, where specified.

Local survey, local installation crews and city-specific soil and storm data behind every design.
IT campuses & data centres, aerospace and defence units
Automotive plants, port & petrochemical facilities
Pharma & life sciences plants, data centres
Automotive & EV plants, engineering MIDC units
How to run a risk assessment, pick a protection level, and translate rolling sphere radius into a buildable air termination layout.
The three field methods used on Indian sites, when each is valid, and the mistakes that produce falsely low readings.
Using foundation reinforcement as an earth electrode lowers impedance, saves land and is explicitly permitted by IS 3043 and IEC 62305-3.
DFMHUB manufactures ARK Make lightning protection system components — air terminals, conductors, clamps, test links, surge protection devices — and a full structural earthing range including copper bonded rods, chemical electrodes, exothermic weld kits, earth bars and inspection chambers, all type-tested to IEC 62561.
Every system is designed and installed to IS/IEC 62305 Parts 1-4, IS 3043:2018, IEC 62561 Parts 1-7, National Building Code 2016 Part 8, and IEC 61643 for surge protection. NFPA 780 and NF C 17-102 are followed where a project specification calls for them.
Yes. DFMHUB offers a single-source package: risk assessment, system design, manufactured components, site installation by trained crews, earth resistance and continuity testing, and a documented handover pack for fire NOC, insurance and audit purposes.
We deliver projects across India with dedicated engineering teams for Bengaluru, Chennai, Hyderabad and Pune, and supply ARK Make products nationwide to EPC and electrical contractors.
