Most of the words "Optical Fiber Distribution Box" may sound strange, but those who come into contact with it will not be so strange. So today, China Fiber Optic Splice Closure Manufacturers will introduce the basic knowledge of optical fiber distribution boxes in detail for everyone.

Distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box) and metering cabinet (box), and is the final equipment of distribution system. Distribution cabinet is the general designation of motor control center. The power distribution cabinet is used in occasions with relatively scattered loads and fewer circuits. The motor control center is used for occasions with concentrated load and more loops. They distribute the electric energy from a circuit of the upper distribution equipment to nearby loads. This class of equipment shall provide protection, monitoring and control of load.

(1) Class I power distribution equipment is collectively referred to as power distribution center. They are centrally installed in the substation of the enterprise and distribute electric energy to the subordinate distribution equipment in different locations. This class of equipment only depends on step-down transformer, so the electrical parameter requirements are higher and the output circuit capacity is larger.

(2) Secondary power distribution equipment is the general designation of power distribution cabinet and motor control center. The power distribution cabinet is used when the load is scattered and the circuit is less. The motor control center is used for occasions with concentrated load and more loops. They distribute the electric energy from a circuit of the upper distribution equipment to nearby loads. This class of equipment shall provide protection, monitoring and control of load.

(3) The final power distribution equipment is always called lighting power fiber distribution box. They are far away from the power supply center and are scattered small-capacity power distribution equipment.

What are its installation requirements? The installation requirements of distribution boards (boxes) are: the distribution boards (boxes) shall be made of non-combustible materials; Open power distribution boards can be installed in production sites and offices with low risk of electric shock. Enclosed cabinets shall be installed in processing workshops, casting, forging, heat treatment, boiler rooms, woodworking rooms and other places with high electric shock risk or poor working environment. Closed or explosion-proof electrical facilities must be installed in hazardous workplaces with conductive dust or flammable and explosive gases. All electrical components, instruments, switches and circuits of the distribution board (box) shall be arranged neatly, installed firmly and operated conveniently. Floor mounted plate (box) bottom surface should be 5 ~ 10 mm higher than the ground; The height of the center of the operating handle is generally 1.2～1.5m;; There are no obstacles within the range of 0.8～1.2m in front of the plate (box); The connection of protection wires is reliable. Outside the board (box), there shall be no naked charged body exposed. Electrical components that must be installed on the outer surface of the board (box) or the distribution board must have reliable screen protection.
