The switchgear is of box-type metal-enclosed fixed structure and the cubicle consists of profies and G profiles assembled by several connection pieces .It is divide into four compartments ,namely busbar compartment .CB compartment ,metering compartment and cable compartment .The parts processing shall be made by CNC punching machine ,CNC bending machine and sophisticated machines provided in CNC processing center ,ensuring high precisopm of form ,position and dimension ,fast and accurate making ,fiexible for combination of different options ,which can meet different demands form customers . Main features 1.The cubicle is of assembled structure ,no welding ,high mechanical strength and artistic apperance . 2.The rear upper part is for GN30-12 rotarydisconnect switch and lower part for GN19-12C disconnect switch .The mechanical interlock device operated as per procedures can provide reliable safety protection for the operation personal and equipment . 3.The main switch adopted is of monoblock type ,options such as ZN63-12(VS1-12)and VD4-12 4.Compulsory mechanical locking method is employed in the interlocks among main switches ,disconnectors and cubicle door to meet the ‘five -proof ‘interlock function,enjoying random combination with ring main unit .
1. Ambient air temperature: -5~+40 and the average temperature should not exceed +35 in 24h. 2. Install and use indoors. Altitude above sea level for operation site should not exceed 2000M. 3. Relative humidity should not exceed 50% at max temperature +40. Higher relative humidity is allowed at lower temperature. Ex. 90% at +20. But in view of the temperature change, it is possible that moderate dews will produce casually. 4. Installation gradient not exceed 5. 5. Install in the places without fierce vibration and shock and the sites insufficient to erode the electrical components. 6. Any specific requirement, consult with manufactory.
