Products Description
Designed for extreme operating environments, the Wire Clamp Terminal with Screw enhances its adaptability and reliability in extremely cold, high-temperature, and high-humidity environments through material selection, structural optimization, and process improvements. Utilizing weather-resistant materials and anti-corrosion coatings, combined with a stable locking structure design, it can operate stably over extended periods in a wide temperature range of -40℃ to 125℃, as well as in high-humidity and salt spray environments. It is suitable for the wiring needs of outdoor photovoltaic systems, energy storage systems, charging piles, and industrial control equipment. As a customizable product, it supports optimization of structure and materials according to different operating conditions, providing customers with targeted solutions for extreme operating conditions.
Metal Forming Process
Weather-Resistant Frame Stamping
The terminal frame is formed by stamping steel, and heat treatment enhances the material's low-temperature toughness and high-temperature stability, ensuring the Cage Clamp Screw Terminal frame remains free from deformation and breakage under wide temperature conditions.
Automated Corrosion-Resistant Coating
An automated electroplating production line achieves uniform control of the zinc plating layer, with a thickness of≥8μm. Passivation treatment further enhances the coating's weather resistance and corrosion resistance, verified through salt spray testing.
High-Stability Cold-Ford Screw Forming
Pre-Assembled Screw Clamp Terminal screws are produced using a cold-formed process. Combined with heat treatment and galvanizing, this improves the screws' low-temperature toughness and corrosion resistance, ensuring the threads do not strip or rust under extreme operating conditions.
Automated Assembly and Clearance Control
An automated assembly line enables precise assembly of the pre-fitted screw terminal clamp, controlling the clearance between the frame and screws to ensure good contact performance under thermal expansion and contraction conditions.
Advantages Compared to Competitors
Compared to ordinary industrial terminals
Ordinary terminals are prone to rusting, loosening, and aging in extreme environments, leading to a high failure rate. Our Integrated Screw Clamp Terminal is specially designed to withstand harsh environments, significantly reducing the failure rate.
Compared to imported high-end terminals
Imported terminals, while of high quality, are expensive, have long lead times, and are difficult to find spare parts for. Our Galvanized Steel Screw Terminal Clamp meets or even exceeds the performance level of imported terminals, but is more competitively priced and readily available.
Compared to inexpensive terminals
Inexpensive terminals often cut corners and use inferior materials, failing quickly in extreme environments. We insist on using high-quality materials to manufacture our Zinc Alloy Screw Wire Terminal. Although the initial investment is slightly higher, in the long run, it reduces maintenance costs and downtime losses.
Application Scenarios
Outdoor power distribution in high-altitude and cold regions
Suitable for outdoor circuit breakers and transformer terminals in environments as cold as -40℃. As the core clamping unit of the Breaker M4 Screw Terminal Block, it ensures a reliable power supply in extremely cold winter conditions.
01
Tropical High-Humidity Industrial Plants
Used in textile, paper, and food processing plants with humidity levels above 95% RH for relay wire clamp terminals and power distribution terminal blocks, suppressing corrosion failure in humid and hot environments.
02
Coastal Salt Spray Environments
Suitable for C3-C4 corrosion level environments such as ports, offshore platforms, and coastal substations. Nickel-plated products effectively resist salt spray corrosion.
03
High-Altitude Day-Night Temperature Variation Scenarios
In high-altitude areas with day-night temperature variations exceeding 40℃, the thermal expansion matching design ensures that screw terminal wire connectors remain secure over long periods, reducing maintenance frequency.
