The protective wiring method in which the metal part of the electrical appliance (that is, the metal structural part insulated from the live part) which may be charged after the insulation material is damaged or in other cases is reliably connected by the conductor and the grounding body. The grounding protection system has only phase and neutral lines.
Lightning protection equipment is through modern electricity and other technology to prevent the equipment being struck by lightning. Lightning protection equipment can be divided into power lightning protection, power protection socket, antenna feeder protection, signal lightning protection, lightning protection testing tools, measurement, and control system lightning protection, earth pole protection.
Surge Protection Device SPD is also named arrester, All surge protectors for a specific purpose are actually a kind of rapid switch, and the surge protector is activated within a certain voltage range. After being activated, the suppression component of the surge protector will be disconnected from the high-impedance state, and the L pole will be turned into a low-resistance state.
Power over Ethernet (PoE) Surge Protector model ND-CAT 6A/EA is specifically designed to protect communication devices connected via Ethernet LAN from lightning surge entering through network cables.
The SCB (Surge Circuit Breaker) dedicated backup protector provides professional backup protection for the SPD (Lightning Protection Device) that protects the power supply.
