UK Series Terminal Blocks

UK-series terminal blocks feature convenient installation, precise operation, standardized accessories, flexible potential distribution, and consistent appearance and labeling. They are available in a wide range of models, including general‑purpose types (such as UK1.5, UK2.5B, etc.) and specialized variants (such as miniature, double‑in/double‑out, and double‑layer designs). Constructed with a nylon PA6 insulating housing, high‑precision brass conductive blades, and a stress‑relieved brass crimping frame and screws, these terminal blocks are extensively used for wire connections and signal/power distribution in industrial automation, power systems, rail transit, and other applications.

PT terminal block

PT terminal blocks are specialized connection components for the secondary circuit of potential transformers (PTs). Their conductive parts are made of red copper, while the insulating housing is nylon, ensuring safety. The design balances robustness with ease of use: wires are secured either by bolted fastening or spring‑clamping, providing vibration resistance and preventing loosening, thereby minimizing contact resistance. Certain models feature voltage isolation, phase‑marking, and short‑circuit protection. With a wide range of specifications to accommodate various wire gauges and electrical parameters, these terminal blocks are extensively used in substations and distribution rooms, safeguarding voltage signal transmission and maintaining power system stability.

Junction box / switch terminal / multi-way terminal

A junction box is a device that protects electrical connections. Its housing is made of high‑quality plastic, offering flame retardancy, water and dust resistance, and corrosion protection, making it suitable for a wide range of demanding environments. Inside, it features wiring terminals and other components, with wires connected via screws or snap‑in fasteners; some models also include waterproof sealing rings to enhance safety. Available in a variety of styles—such as surface‑mounted, flush‑mounted, and explosion‑proof—it is widely used in building electrical wiring, smart homes, power systems, industrial automation, outdoor lighting, new energy applications, and more. It safeguards connection points, prevents short circuits and leakage currents, facilitates maintenance, and ensures the reliable operation of electrical systems.
