Isolating spark gaps, also called gas discharge tubes (GDT), is a SPD composite that reduces surges from the electric system. Isolating spark gaps are usually tubes containing inert gas that conduct when the voltage exceeds a specific threshold. The main advantage of isolating spark gaps is that it facilitates bonding between systems, such as grounding and data systems. Kumwell provides isolating spark gaps alongside one-stop services as a total solution for any industry; the highlighted isolating spark gaps are listed below.
For Equipotential Bonding
Kumwell KZ.ISG100 are separating high powers gas discharge tubes intended for equipotential bonding of installation parts of buildings, which are not interconnected. Recommended installation is inside the buildings, outdoors in the damp rooms and the subterraneous areas. For lightning protection equipotential bonding under IEC 61024-1 and IEC 62561-3.
For Explosion Hazards Areas
Kumwell KZ.ISG100-EX is separating high-power gas discharge tube for use in explosion hazard areas. It is an explosion-proof gas discharge tube with a flexible connecting cable for equipotential bonding according to IEC 61024-1 and also for use in IT installation according to IEC 60364-5-54. It complies with EN 50014 and EN 50028 standards. It is recommended for insulated flanges and insulated screw joints bridging in cathodic protected parts of industrial technology.
For Railway Network Overvoltage Protection
Kumwell KZ.ISG100-RW is recommended to install this limiter between the current return path and non-electrified parts of structures adjacent to the rails. In case of overvoltage, KZ.ISG100-RW generates a durable conductive path between the overloaded area and the railways substation. This results in increased current loads sensed at the substation, tripping the safety switch and thus protecting personnel and equipment
