Electrically insulating surge arrester / type 1 - max. 144 kV
CG presents ZNO porcelain clad ZLA2 surge resistors. Since 1994, CG has been making metal oxide surge arresters of station type with line discharge class-2. They collaborated with M/s Hitachi Limited, Japan for technical expertise. Common applications of these surge arresters is to protect capacitor banks, transformers, and others. ZLA2 surge arresters can also serve in wind mills and other special applications.

Type 1 surge arrester / for electrical networks - max. 420 kV
The ZNO porcelain CLAS ZLA3 is the result of GC's experience in the industry, being manufactured from metal oxide with technical know-how from M/s Hitachi Limited in Japan. The surge arresters in this series are designed for the protection of transformers, as well as capacitor banks and applications that come with high energy requirements.
The surge arresters in the CH ZLA3 series are used in special applications such as shunt reactor protection and rolling stock projects.

Type 1 surge arrester / DIN rail - 5 - 150 KA, 275 - 440 V | CCS01
The surge arrestor is made up of a semi-conductor valve element that only opens at specific conditions. It has a relatively high resistance between the protected conductors and earthing circuit under normal conditions. Voltage increase due to pneumatic environments or system crash, the valve element opens and directs the excess voltage to the grounded circuit. After reversion of the normal voltage the valve element closes. It is also is capable of enduring high overloading in a short amount of time.

Type 1 surge arrester / lighting - 10 - 30 kVA | CLA
CLA series are low-cost surge and lightning arrestors specially designed for airfield lighting application on runways, taxiways or aprons. They meet all international standards, and are efficient in protection against over voltages and surges resulting from various origins :
External: Atmospheric influences, static loads, lightning strikes, induced surges
Internal: Modification of the electrical stability of the installation in normal operation (switching oscillations) or irregular operation (arcing, ground faults)
Advantage :
Operation security, risks of wrong operation, granted limit of the ignition voltage
Maintenance optimisation, CLA can be easily added in any existing installations, or disconnected for replacement
Internal constitution, the CLAs active part consists of non-linear resistors, molded with polyurethane
