♦ MAIN CHARACTER of TSTLP Isolating/Lightning Spark Gap for Lightning Protection
1, For indirect connection / earthing of functionally isolated parts of installations under lightning conditions
2, For bridging insulating joints, insulating (Pipeline) Flanges against damage caused by overvoltages, etc. in cathodically
protected pipe sections, to avoid failures, downtimes, and even leaks on pipelines and protect sensitive insulating
flanges against sparkover, which in turn to ensures smooth operation of the pipeline.
3, For safer installation in Ex zone 1 (gas) or 21 (dust)
4, Extremely low sparkover voltage & high alternating current withstand capability
5, Specially used for lightning equipotential bonding in Hazardous Areas
6, Approval according to ATEX directive 2014/34/EU, European Explosion-Proof Ex Certificate Available
| INSTALLATION INSTRUCTION Applied for in-doors & out-doors,in damp rooms as well as underground installation. |
