15kV American Cable Branch Box

● Numbering description

● Characteristics of DFW type 15kV American Cable Branch Box

◆ Design feature

▶Common box design: all cable connectors, switches and other components are integrated in a metal box, with compact structure and small space occupation.

▶Low modularity: Compared with the European branch box, the American branch box has weak expansibility, and usually adopts a fixed number of circuits (such as 2~6 circuits).

▶Metal shell protection: the box is mostly made of stainless steel or galvanized steel, and the protection level is generally IP54 (dustproof and splash-proof), and some high-end models can reach IP65.

◆ Cable connection mode

Using American cable accessories

▶15kV American Cable Branch Box use a detachable connector (Loadbreak Connector), such as 200A or 600A elbow plug, to support live plug (special operating rod is required).

▶Cable joints are fully insulated or semi-insulated, and some live parts may be exposed, so it is necessary to cooperate with insulating protective caps.

▶Suitable for a variety of cables: copper cable or aluminum cable is supported, and the cross section usually ranges from 50 mm to 500 mm.

◆ Safety and protective performance

▶DFW type 15kV American Cable Branch Box is Fully enclosed structure: reduce the external environmental impact and reduce the risk of electric shock.

▶Built-in arrester (optional): prevent overvoltage impact and protect cables and equipment.

▶Fault indication function (some models): equipped with flip-flop or LED fault indicator, which is convenient to locate the fault point quickly.

◆ Adaptability to environment

▶Strong weather resistance:15kV American Cable Branch Box it is suitable for working environment of -30℃~+50℃ and is suitable for long-term outdoor operation.

▶Anti-corrosion treatment: the surface of the box body is sprayed with plastic, galvanized and other processes to resist salt spray and corrosion.

◆ Installation and maintenance

▶Convenient installation: usually wall-mounted or floor-mounted installation, suitable for narrow spaces.

▶Simple maintenance: fully sealed design, basically maintenance-free, only need to check the joint status regularly.

▶Live-line operation (some models): use special insulating operating rod for plugging and unplugging, so as to reduce the power outage time.

◆Limitations

×Poor scalability: the number of loops is fixed, and the equipment needs to be replaced for later capacity expansion.

×Low protection level: some models are not as dust proof and waterproof as European branch boxes.
