KYN61-40.5 is the 35KV class switchgear that is developed by bringing in the foreign technology. It is in line with GB3906, IEC-298, DL404 and other standards. It is applicable to the system of three-phase AC 50Hz, rated voltage 40.5KV for the use of power plant area, substation and large industrial mining enterprises to accept and distribute the electric power. It can control, protect and detect the line.
Extra-low voltage, in electricity supply, is one of several means to protect against electrical shock. The International Electrotechnical Commission and its member organizations define an ELV circuit as one in which the electrical potential of any conductor against earth is not more than either 25 volts RMS for alternating current, or ripple-free 60 volts for direct current under dry conditions. Lower numbers apply in wet conditions, or when large contact areas are exposed to contact with the human body.
The IEC defines three types of extra-low-voltage systems, which are distinguished by their successively more restrictive safety properties.
