How Do Ukk Junction Boxes Ensure The Normal Operation Of Rail Transit Systems?

The single pole distribution block terminal block, a rail-mounted branch terminal, is widely installed in distribution cabinets, control cabinets, and station equipment enclosures. Typical models, such as the UKK series, cover specifications from 80A to 500A, and their modular layout facilitates on-site wiring.

During wiring, the modular distribution block terminal block provides a "multiple-path" structure, allowing the main feeder to branch through the terminal box to vehicle traction systems, station lighting systems, signaling equipment systems, etc. This structure unifies the power distribution path to the terminal box while retaining space for jumpers and branch circuits.

During rail transit construction and maintenance, the terminal block 250a terminal block facilitates wiring standardization. It features a plug-in rail mounting system for quick disassembly, replacement, or branch expansion. The contact materials are made of tin-plated or nickel-plated copper, and the plastic housing is made of materials such as PA66 or other flame-retardant grades.
