WCJG/WCJG/WCJE/CER Copper Bolted Type Power Connector Accessories

          WCJG-H                                                 WCJG-T                                            WCJE                                        CER

High-Purity Conductive Base: Forged and die-cast from T2 (99.9% pure) copper, offering high conductivity and low resistivity. It minimizes heat generation and voltage drop, supports current-carrying requirements for 10–120mm² cables, and meets the demands of high-current power distribution applications.

Corrosion-Resistant Surface Treatment: Tin or nickel plating isolates the metal from air and moisture, providing oxidation and corrosion resistance. It prevents oxidation and blackening in outdoor, humid, or acidic/alkaline environments, ensuring stable conductivity over long-term use.

Excellent Heat Dissipation: The copper base offers superior thermal conductivity, rapidly dissipating heat during heavy-load operation to prevent terminal overheating or ablation. It is suitable for continuous, long-term operation in power distribution cabinets, power grids, and electromechanical equipment.

Crimp-Free and Solder-Free Process: Cables are secured by tightening bolts, eliminating the need for crimping tools or soldering. This allows for rapid on-site installation, accommodates both copper and aluminum cables, and saves on the cost of specialized tools.

Adaptive Wire Gauge Range: Available in multiple series (WCJG H/T types, WCJE, CER) covering the full 10–120mm² cable range. A single terminal model can accommodate cables of various cross-sections within a specific range, simplifying inventory management and selection.

Anti-Loosening Locking Design: Equipped with high-strength carbon steel bolts and anti-loosening washers. Once tightened, the clamping force is uniform, providing vibration resistance and preventing cable detachment—ensuring reliable connections without arcing in environments subject to vibration, such as automotive, wind power, and industrial settings.

Reusable and Detachable: Can be disassembled for maintenance. There is no need to cut cables or discard terminals when rerouting or upgrading capacity, significantly reducing consumable costs compared to disposable crimp-style copper lugs.

Comprehensive Product Range: Includes WCJG-H (straight-through), WCJG-T (branch/T-tap), WCJE (parallel groove), and CER (post-style) models. This series covers all scenarios—including cable splicing, branching, equipment output connections, and grounding—meeting diverse power distribution wiring needs with a single product line. Copper-Aluminum Compatibility: Allows for direct connection of copper and aluminum conductors, resolving the electrochemical corrosion issues associated with direct copper-aluminum contact and eliminating the need for separate transition terminals.

Standards Compliance: Complies with international electrical standards DIN46267 and IEC61238-1; holds CE, ISO9001, and SGS certifications; suitable for domestic and international power distribution projects, ensuring hassle-free export compliance.

High Mechanical Strength: Manufactured via integrated forging, resulting in a dense structure free from porosity or cracks; offers excellent tensile and bending resistance, ensuring the component does not crack or deform during tightening; comes with a standard warranty of over 12 months.

All-Weather Suitability: Suitable for indoor distribution cabinets, outdoor overhead lines, photovoltaic systems, construction machinery, and distribution transformer grounding; ensures stable operation in high/low temperatures and rainy or snowy conditions.
