Pfisterer High Voltage Surge Arresters up to 52kV

Pfisterer Connex Inner Cone Plugs

Pfisterer MV-Connex Surge Arresters Up To 52kV 

 

Pfisterer Connex surge arresters protect switchgear and transformers equipped with plug-in type high voltage bushings, 6.6kV up to 52kV . The high voltage surge arresters are connected to the switchgear transformer and prevent the entry of excessively high surges. Surge arresters are particularly effective in limiting surges caused by reflected travelling waves and switching overvoltages.

The Standard for surge arresters IEC 60099-4 is applicable to these devices. The dimensions of the plug-in termination system comply with EN 50180/EN 50181. 

Pfisterer MV-Connex Surge Arrester Features

• Metal-enclosed
• Fully-insulated
• Touchproof
• Free from arcing
• High short-circuit protection
• Maintenance-free
• For outdoor and offshore use
• Protection class IP 66 

 

HV Surge Arresters - Pfisterer Connex - Specification

Pfisterer Connex high voltage surge arresters are to DIN VDE 0675 and IEC 99-4 and the dimensions of the plug-in termination system comply with EN 50180/EN50181.

Surge Arrester Design: the live part consists of metal oxide resistors without spark gap. The resistors possess a high thermal stability ensured by suitable dimensioning - the live parts are enclosed by a silicone rubber jacket that provides insulation against the metal housing. The corrosion resistant aluminium housing renders the surge arrester intrinsically safe ensuring optimum high voltage electrical safety for personnel. The metal housing provides a hermetic sealing of the live parts against environmental influences including moisture and pollution. The HV plug-in surge arrester is designed to fit the inside cone plug-in termination system and is available in size 1, 2 and 3 for high voltage protection up to 52kV. The cable termination is attached via flange to the HV electrical equipment - surge arresters are complete with corrosion-resistant fracture membrane that opens the arrester in case of an internal fault and allows for a defined axial pressure relief on the bottom of the surge arrester without any damage to the plug-in high voltage electrical system.
