Product Description

Kyn28-12 High Voltage Metal Cald Switchgear/Swtich Cabinet

OVERVIEW
KYN28-12 metal armored draw out switch equipment (hereinafter referred to as the switch cabinet) is a new product designed and developed by domestic and abroad advanced manufacturing technology, suitable for 3.6 ~ 12 KV three-phase AC 50 Hz power grid, for receiving and distribution of electrical energy, and for purposes of circuit controlling, monitoring and protection. Can be used for single busbar, single section busbar system and double busbar system, handcart type of the circuit breaker, easy maintenance. Mainly used in power plants, industrial and mining enterprises distribution and hotel area, the urban construction and the petrochemical sector, etc., for purpose of controlling protection, power distribution monitoring.

TECHNICAL CHARACTERISTICS
• The structure of cabinet is made from several coated aluminum zinc plate which bolted after multiple bending by CNC processing, the complete unit is composed of two main components which are cabinet and middle pull out parts • All operations are conducting under the cupboard door closed
• The cabinet separates into four compartments, the protection grade of the shell is IP4X, it is IP2X when the door of the circuit breaker chamber open. High protection grade can prevent the invasion of clutter and pest
• Simply to replace the circuit breaker, and handcart has good exchange performance
• Cabinet can be installed against the wall, maintain from the front side to reduce the occupied area • There is enough space in cable chamber, abundant cables can be connected
• Circuit breaker chamber and cable chamber can add heater separately to prevent condensation and corrosion
• Circuit breaker chamber and cable chamber can add lighting device according to users' requirements for convenience of maintenance and repair With overhead outlet, cable access and other functional programs, it can be various forms of electricity distribution equipment by arranging and assembling.



WORKING CONDITIONS
• Ambient temperature: -25ºC~+40ºC
• Altitude: ≤2000m (If it is more than 2000m, please specify when ordering)
• Relative humidity: ≤95%(+25ºC)
• Earthquake intensity: ≤8 degrees Installation Environment: In the place where there is no fire, no explosion hazards, no serious pollution, no chemical corrosion and violent vibration.
