When the vessel is sailing in the harsh conditions of the polar seas, the equipment on the open deck is subjected to huge tests. The materials of this equipment cannot be lower than the temperature and cold, but the normal use of the equipment must be guaranteed in this low temperature and cold environment.

Electric heating system can not only heat electrical equipment, but also non-electrical equipment, which is a relatively bright and reliable application method. Therefore, the use of an electric heating system to protect equipment from freezing is a common method of protection against heating on polar ships.

The entire electric heating system includes the following parts, a switchboard, an electric heating connection box, a heating cable and a temperature sensor. This article focuses on electric heating junction boxes and electric heating cables.

Electric Heating Distribution Box

As a connecting element between the power cable and the electric heating system in the electric heating system, the electric heating connecting box is connected to one end to the power cable, and the other end to the electric heating cable. Be installed outdoors and as close as possible to the equipment that needs to be heated. Requirement 50 ℃, protection class not less than IP56.

Our electric heating junction boxes are fully consistent with the low temperature conditions of the polar region, and the protection level of our electric heating junction boxes is IP66.

Electric heating cable

Electric heating cables suitable for polar transport vessels, usually we recommend self-regulating medium temperature electric heating cables and self-regulating high temperature electric heating cables. Parameters of two self-regulating heating cables:
