Introduction

GB/T 33588 "Lightning protection system components (LPSC)" aims to establish the lightning protection system components designed and installed according to the IEC 62305 series of standards.

The requirements and test methods for various components used in the life protection system (LPS) are intended to consist of eight parts.

--- Part 1: Requirements for connectors. The purpose is to establish the requirements and test methods for metal connectors in lightning protection systems.

--- Part 2: Requirements for lightning terminals, down conductors and grounding electrodes. The purpose is to establish the requirements for the metallic conductors that constitute lightning terminals and down conductors.

Requirements and test methods for metal grounding electrodes (non-"natural" conductors) and metal grounding electrodes that constitute the grounding system.

--- Part 3: Requirements for Isolating Spark Gaps (ISGs). The purpose is to establish the requirements for isolating spark gaps in lightning protection systems and test methods.

--- Part 4: Requirements for conductor fasteners. The purpose is to establish the metal fasteners used to fix and support air terminals, down conductors and grounding devices.

Requirements and test methods for fasteners for metal and non-metallic conductors.

--- Part 5: Requirements for grounding electrode detection boxes and grounding electrode seals. The purpose is to establish grounding electrode detection boxes installed underground Requirements and test methods for terminal boxes and earthing electrode seals.

--- Part 6: Requirements for lightning strike counters (LSCs). The purpose is to establish the requirements and test methods for lightning strike counters.

--- Part 7: Requirements for grounding resistance reduction materials. The purpose is to establish the requirements and tests for grounding resistance reduction materials in lightning protection systems method.

--- Part 8: Requirements for isolation components of lightning protection systems. The purpose is to establish the requirements for insulation supports and insulation down conductors and their special tight Requirements and test methods for firmware.

This document specifies the requirements for grounding electrode test boxes (terminal boxes) and grounding electrode seals installed underground, and describes the corresponding tests.

method.

Lightning protection system components (LPSC) are also suitable for use in hazardous environments. Components installed in such conditions must take into account necessary additional requirements.

NOTE. For different requirements and test procedures, see EN 124 (all parts) and EN 1253 (all parts).
