| Brand | ROCKWILL |
| Model NO. | GTTLA Series GIS Tank-Type Lightning Arresters |
| Rated voltage | 220kV |
| Series | GTTLA Series |
Overview
GIS tank-type lightning arresters employ a metal-enclosed housing with SF6 gas as the internal insulation medium. They utilize single-column or multi-column resistor disc columns in parallel as the core, covering AC voltage ratings from 110kV-500kV.
Features
Compact Structure and Small Footprint
The tank-type structure and rational internal component layout result in a compact overall structure and reduced footprint.
High Reliability
High-performance resistor discs and reliable sealing structures ensure long-term stable operation in harsh environments with minimal risk of failure or performance degradation.
Excellent Insulation Performance
SF6 gas as the internal insulation medium and single-column or multi-column resistor disc columns in parallel offer superior insulation performance.
Strong Contamination Resistance
The shell material exhibits good contamination resistance, maintaining stable insulation performance in contaminated environments.
