Scope
GB/T 36963-2018 is the English-translated version of 光伏建筑一体化系统防雷技术规范.
GB/T 36963-2018 covers the lightning protection of building integrated photovoltaic (BIPV) systems. It sets requirements for protection against direct lightning strikes, separately for buildings with reinforced concrete or steel structures and for other buildings, with a procedure for choosing the protective measures.
It then deals with protection against the lightning electromagnetic pulse, through equipotential bonding, magnetic shielding and the selection and installation of surge protective devices (SPDs), and with testing and maintenance of the protection.
Informative annexes show installation examples for lightning rods, air-termination strips and cables, grounding arrangements, SPD positions and wiring, and the calculation of UOCMAX.
It applies to the design and construction of new, rebuilt and extended BIPV systems, and existing systems may use it as a reference. It was issued on 28 December 2018 and has applied since 1 July 2019.
