Single-phase CDD Transformer
Scope of Application
The single-phase CDD series marine lighting control and power transformers (hereinafter referred to as “transformers”) produced by our company, under normal usage conditions, are installed on ships, offshore platforms, and other places for lighting, power, communication, or grid isolation applications. This series of transformers is suitable for voltage up to 690V, 750V, with frequencies of 50Hz and 60Hz, and single-phase capacities of 0.05~10kVA. The transformer core is of a core-type structure, made of high-quality cold-rolled silicon steel sheets, which can firmly fix the windings and minimize vibration under usage conditions. The coils are wound with high-quality insulation enameled wire or silk-covered wire, with insulation classes of B, F, and H.
The C(P)SCD series marine three-phase transformers (hereinafter referred to as “transformers”) are used in ships, offshore platforms and other places for lighting, power, communication, or grid isolation under normal usage conditions. This series of transformers is suitable for voltage up to 690V, 750V, with frequencies of 50Hz and 60Hz, and capacities of 1~2000kVA for dry-type self-cooled drop-proof transformers. The transformer core is of a core-type structure, made of high-quality cold-rolled silicon steel sheets, which can firmly fix the windings and minimize vibration under usage conditions. The coils are made of high-quality insulation enameled wire or silk-covered wire, with insulation grades of B, F, H. Protection types: divided into drop-proof (IP21, IP23, IP44).
