Breaking capacity up to 50 kiloamperes Mining HV Distribution Cabinet featuring operating temperature range minus 25 degrees Celsius to plus 55 degrees Celsius for mining power control

Product Description:

Technical Parameters:

The rated voltage options available are 12kV, 24kV, and 36kV, which correspond respectively to distribution network systems operating at 10kV, 20kV, and 35kV. This alignment ensures compatibility with commonly used voltage classes within power grids.

Regarding frequency, the equipment supports both 50Hz and 60Hz, making it compatible with the majority of global power grid standards. The rated current for the main circuit can be 630A or 1250A, where 630A is the standard configuration, suitable for long-term operation.

The rated short-time withstand current (Icw) is available in several ratings: 16kA, 20kA, 25kA, and 31.5kA, all with a duration of 3 seconds according to national standards. The rated peak withstand current (Ip) is designed to be 2.5 times the short-time withstand current, with options of 40kA, 50kA, 63kA, and 80kA.

Insulation levels are defined by power frequency withstand voltage and lightning impulse withstand voltage. For example, the 12kV class offers a power frequency withstand voltage of 42kV sustained for 1 minute, and a lightning impulse withstand voltage of 75kV. These indexes increase progressively with higher voltage classes.

Protection classes include IP4X for cabinet shells, providing dust-proof protection, and IP67 for switch components, making them suitable for outdoor immersion scenarios. The earthing switch can handle a rated current of 2000A for short-time conditions, ensuring safety under short-circuit faults.

The operating mechanism supports both manual and electric operation modes. The electric operation allows for remote control capabilities, and an energy storage motor option is available for enhanced performance. Fuse configurations are compatible with XRNT type high breaking capacity fuses, covering rated currents from 6.3A up to 400A, primarily intended for transformer protection.

The equipment can operate in various environmental conditions. The ambient temperature range is from -25℃ to +40℃, with altitude up to 1000 meters without customization. For higher altitudes or special environments, customization is required. Humidity tolerance reaches up to 95% without condensation, and specialized high-altitude or anti-corrosion models are available.

Cabinet materials include cold-rolled steel plates coated with plastic spray, as well as stainless steel options (304 or 316 grades). Stainless steel variants are particularly suitable for coastal regions and chemical corrosion environments, providing enhanced durability.

The primary circuit schemes are flexible, offering configurations such as 2-in-2-out, 3-in-3-out, and terminal types, which can be customized based on the topology of the distribution network. Secondary control options include intelligent measurement and control units, temperature and humidity controllers, and fault indicators, all of which support integration with SCADA systems for remote monitoring.
