All marine transformers are built on our dry type transformers basics of production in accordance with the technical requirements of the IEC.60076, and be approved by CCS.

Ⅰ、Purpose and Service conditions

1. Purpose
Marine transformers are used for lighting, power , intercommunication of isolation of power lines on ships.
2. Service conditions
A height above sea-level not exceeding 1000m;
A temperature of ambient air not below -25℃ and not above +45℃;
Relative air humidity: ≤95%
Be influenced by dew, oil and salt vapor ，molds.
There are vibrating，colliding, during ships transporting.
Swing with angle up to 22.5°，slopping with 15°or below during ships transporting.

Ⅱ、Structure

transformer are drip-proof ，dry type ，natural air-cooled，floor mounting type.
Insulation class B、F or H.
Three phase transformers are produced into three types, includes one three phase transformer designed a unitary and three or four single phase transformers in fit together type. The transformer enclosures are made of the cold-rolled steel plate and designed for air circulation and drip-proof, rat proof. The terminal board and tap changing boards
are provided inside the enclosure. External input &
output cables can be easily connected to the terminal
board through the cable glands mounted on the left
and/or right side of enclosure.
