KYN18A-12 AC indoor withdrawout metal-clad is the central vacuum switch cabinet which mainly applies the ZN12-12 vacuum circuit
KYN18-12 removable AC metal-clad switchgear is a new product designed and d eveloped by HEAG group based on advanced foreign de sign and technology. Its outstanding advantages as follows:
1. The enclosure is completely made of aluminium-zinc plated steel sheet which processed by CNC machine, then assembled with bolts. The structure is free from corrosives and deformation.
2. LV compartment and HV compartment are completely separated by metal sheet. It prevents from spreading to other p arts due t o IP4X of protection degree.
3. Effective anti-fault interlock assure that each operation step is according to specified procedure.
4. Integra ted and reliable performance assure that it is free from maintenance.
5. The handcart is flexible to draw out and change.
6. Earthing switch with rapid open-close operation function has such capacity on short circuit current.
7. Secondary wiring will be buried in metal channel to prevent damages from internal failures.
