GLX24-C cable panel, free combination, full modularization, free maintenance

GLX24 series SF6 Ring Main Unit is an estensible, SF6 insulated siwtchgear, with rated voltage of 12&24kV. All its HV live parts are contained in an air-tight gas tank, which is made from stainless steel of 3mm. The whole switching assebly is SF6 insulated, and free from any external influence, ensuring it great reliability of service and maintenance free. By plug-in type busbar extension,

GLX24 series RMU can be of free combination and full modularization. The busbar extension has passed type test for power and thermal stalility, and is fully insulated and shielded, exhibiting high reliability and safety.

GLX24 series Ring Main Unit is suitable for all MV network up to 24KV, all compact power stations, power distribution substations in all important industries, such as petrol-chemical industry, metallurgical and mining industries, and all transformer substations and wing power system.

Conformity with standards

GLX24 series meets the following international standards and national standards:

GB11022-1999                  IEC60694:2002

GB3906-2006                    IEC62271-200:2003

GB3804-2004                    IEC60265-1:1997

GB1984-2003                    IEC62271-100:2001

GB16926-1997                  IEC62271-105:2002

Advanced facilities and process 

With the laser cutting and puching machines imported from TRUMPF(Germany), the accuracy of re-location can be 0.02mm; the cutting deviation can be less than 0.05mm, which ensures that before welding the gaps between plates of gas tank are smaller than 0.1mmThe three-dimension and five-axis laser welding system, also from TRUMPF, with welding laser beam of 0.1mm and under protection of Helium gas, welds the stainless steel plates, the welding quality equals to bended steel plates, which 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, brings gas leakage rate per year down to less than 0.02%, ensuring the life span of gas tank of over 30 years.

Cable panel is used for in/out cable connection.
