GB/Z 33588.8-2022 (Lightning protection system components (LPSC) - Part 8: Requirements for components for isolated LPS) is available as an English-translated PDF.

GB/Z 33588.8-2022 is the Chinese standard "Lightning protection system components (LPSC) - Part 8: Requirements for components for isolated LPS". Its scope clause reads: This document specifies the requirements and test methods for insulating supports and insulating down conductors and their special fasteners.

Insulating brackets cooperate with air-termination and Use down conductors to maintain proper separation distance; insulated down conductors can reduce the separation distance.

This document does not cover testing of insulating supports and insulating down conductors for use in explosive atmospheres. Performance requirements and test methods for other types of isolation components of lightning protection systems are under study.
