Optical Fiber Distribution Box is the lowest level control and protection facility in the power system, and is the most basic link to ensure the safe operation of the power system.

It has a great chance to contact with workers, but due to its large quantity, wide distribution and low value products, it is often ignored by the power department of the equipment, thus making many optical fiber distribution boxes out of control, causing unsafe factors and increasing the risk of electric shock and electrical fire.

Therefore, we must pay attention to the safe selection and use of optical fiber distribution box.

Second, the choice of optical fiber distribution box protection type optical fiber distribution box protection type should be selected according to the conditions of the workplace.

(a) in the relative humidity is not more than 75%, and no dust, no corrosive gas or vapor, no flammable and explosive substances less dangerous places, the optical fiber distribution box can choose open type.

(2) Protective type shall be used in particularly humid places with relative humidity close to 100% and places with corrosive gas or vapor.

(3) Dust-proof distribution boxes shall be selected for dusty places that can generate a large amount of dust.

(4) Dust-proof type shall be selected for Class H-1 and Class H-2 fire hazard sites with combustible liquid, suspended or accumulated combustible dust or combustible fiber;

In the H-3 fire hazard site with solid combustible substances, the protective type can be selected. (5) Selection of explosive hazardous sites.

Nbstarlite is the choice of China Fiber Optic Splice Closure Manufacturers. We are your safety guarantee.
