Cable Branch Box
Model: DFW-12 European Cable Distribution Box
Application:
European cable distribution box is a kind of cable engineering equipment widely used in power distribution system in recent years. Its main features are bidirectional door opening and the use of wall bushing as the connecting bus bar, which has obvious advantages such as short length, clear cable arrangement and no need for long-span crossing of three-core cables. The cable connector used in this system conforms to DIN47636 standard. Generally, the rated current 630A bolt is used to fix the connecting cable joint.
Features:
● Ambient temperature: maximum temperature: +40℃, minimum temperature: -30℃;
● Wind speed: equivalent to 34m/s (not more than 700Pa);
● Humidity: the average daily relative humidity is not more than 95%, and the average monthly relative humidity is not more than 95%;
● Shockproof: the horizontal acceleration is not more than 0.4m/s and the vertical acceleration is not more than 0.15m/s;
● Inclination of installation site: no more than 3;
● Installation environment: The surrounding air is not obviously polluted by corrosive, combustible gas and water vapor, and there is no violent vibration at the installation site. Note: Please consult our company when ordering this product beyond the above conditions.
