KYN28A-12 Use Environmental Conditions
1. Normal condition
Surrounding air temperature: -10℃～ +40℃
Altitude: 1000M
Relative environment humidity: The daily relative humidity average is not higher than 95%, the monthly relative humidity average is not than higher 90%
Earthquake: The intensity does not exceed 8 degree.
The surrounding air without corrosive or flammable gas or water vapour.
Without a lot of dirtiness and regular fierce vibration, under the severe condition, the intensity meets the first kind requirement.he iron core is made of cold-rolled silicon steel sheet with high magnetic permeability grain orientation. The iron core is a core iron core, a fully miter seam stacked iron core, and its iron core column is a circular section of multi-step steps, and the yoke and iron core are equal sections.
2. special working conditions
When it is used beyond the normal environmental condition stipulated in the GB3906, the user should consult with the manufacture.

KYN28A-12 Structure Introduction
The switch equipment is designed according to GB3906-91 metal armoring seal switch equipment. The rectifier body is made up of the cabinet body and draw-out parts (namely handcart) placed in the middle. See charter 1. The cabinet divides into four separate rooms, the outer covering protection grade is IP5X,when each small room and the circuit breaker is opened, the protection grade is IP2X.It can suspend the inlet, outlet line, cable’s inlet, outlet line and other function plan. After arranged and combined, it can become each kind of plan form of the power distribution equipment. This switch equipment may be installed and maintained from the frontage, therefore it may compose the dual arrangement back to back and be installed against the wall, improving the switch equipment’s security and flexibility and making full use of the occupying area.

1. Commercial Complexes & High-Rise Residential
Modern commercial complexes and high-rise residential buildings require reliable, compact, and fire-safe power distribution equipment.
2. Industrial Parks & Heavy Manufacturing
Industrial parks and heavy manufacturing facilities, including steel mills, cement plants, chemical factories, and automotive assembly lines, consume large volumes of medium-voltage power and require robust, outdoor-rated distribution equipment.
3. PV & Energy Storage Grid Connection
Solar photovoltaic farms and battery energy storage systems (BESS) require dedicated step-up transformer solutions to interface with the medium-voltage grid.
4. Infrastructure — Rail Transit, Healthcare & Data Centers
Critical infrastructure applications, including metro and railway systems, hospitals, and data centers, demand the highest levels of power reliability and redundancy.
5. Municipal & Environmental — Water Treatment & Pumping Stations
Municipal water supply, wastewater treatment plants, and flood control pumping stations present challenging operating conditions for electrical distribution equipment. altitude not more than 1000m;
