Dry Transformer | Fireproof Resin-Cast Power Unit

A:The box-type transformer is suitable for urban residential communities. It has a high degree of integration, occupies a small area, has a clean appearance and low operating noise. It can be directly placed in the green belts or power distribution rooms of the community. The pole-mounted transformer (tower-type transformer) is suitable for suburban or rural communities. It has a low cost and is easy to install. It is erected on utility poles and is suitable for scenarios with dispersed loads.

A:Use copper busbars or cables for connection, with the conductor cross-section meeting the current-carrying requirements; the connection points need to be treated with tin plating or silver plating to reduce contact resistance; install lightning arresters and disconnect switches on the high-voltage side to facilitate maintenance; add insulating covers for the busbars on the low-voltage side and mark the phase sequence; after connection, check the insulation and phase sequence to ensure there are no errors.

A:Dry-type transformers are oil-free and do not have the risks of oil leakage or explosion. They have high fire safety. The volume is relatively small, making them easy to install in the distribution rooms of buildings. The maintenance is simple and they meet the fire protection and space requirements of high-rise buildings.
