Περιγραφή
GPN1-12kV removable AC metal-clad switchgear (short for panel as below) is a new product, designed and developed by us, based on the introduction of advanced foreign design and manufacturing technology. The panel applies to 3.6~12kV 3phase AC 50Hz network for receiving and distributing power energy and also for control, monitor and protection. It can be arranged for single busbar, single busbar sectionalizing system or double busbar. It accords with IEC298 “AC Metal Enclosed Switch and Control Equipment above 1kV and below 52kV “IEC 694 Standard Common Clauses for High Voltage Switchgear “, DIN. VDE ” AC Switchgear at Rated Voltage Above 1kV “, GB 3906 ” 3~35kV AC Metal Enclosed Switchgear and so on. It has perfect and reliable prevention function against misoperation.

1.Advanced process technique for gas tank
The digital-controlled laser cutting and punching system and three-dimension and five-axis laser welding system imported from Germany with ensure the gas tightness and uniformity of all gas tanks.
The fully automatic and integral helium leak detection system, made by SEILER Vakuumtechnik GmbH, through detecting of Helium leakage by mass spectrograph, brings gas leakage rate per year down to less than 0.02%, ensuring the life span of gas tank of over 30 χρόνια.
Advanced process technique for parts .
All epoxy resin insulated parts, including insulated poles, are manufactured by fully-automatic and digitally controlled epoxy resin vacuum mixing/pressure gelatinizing system from Hedrich (Γερμανία) .
The busbar connector, cable connector, end-plug and other silicone rubber insulated parts are manufactured by fully-automatic and digitally controlled silicone rubber mixing/pressure gelatinizing system from VOGEL(Switzerland).
2.Excellent solutions for products
With small and compact structure, the basic functional units K, T, V, B and C have uniform dimension: 350*800*1380 mm (width*depth*height) .
Complete solutions:
Single version: load break switch unit, switch-fuse unit, vacuum circuit breaker unit, busbar subsection unit, cable unit, metering unit, και τα λοιπά.
Block version can be made up of two, three, four, five or six functional units.
Single units and block version can be connected by busbar connectors flexibly.
3.Strong adaptability to the environment
The primary conductive system is fully sealed in the SF6 gas tank and will not be influenced by the outside environment, independent of the impact of dew, dust, salt fog, και τα λοιπά. Επομένως, GPR-24 series can be applied at various severe service conditions.
