Manufactured from oxygen‑free copper (Cu-ETP) with silver plating, the plate achieves >98% IACS conductivity, minimizing voltage drop and power loss in critical circuits.
Rated for 250 A continuous current, the plate safely distributes power from heavy‑duty alternators and battery banks, supporting all electrical loads without overheating.
Electrolytic silver plating combined with an epoxy insulating layer provides outstanding protection against moisture, salt, and chemicals, ensuring long‑term conductivity.
Integrated M8 stainless steel studs and precision‑drilled mounting holes ensure secure, vibration‑proof connections that maintain low resistance even under severe chassis movement.
This genuine electrical connecting plate is the factory‑specified power distribution component for the following SINOTRUK Howo systems:
The WG9925760004 Electrical Connecting Plate is precision stamped from high‑purity oxygen‑free copper (Cu-ETP), a material chosen for its exceptional electrical conductivity and resistance to thermal fatigue. The plate is then electrolytically silver‑plated to a thickness of 10 µm, providing a low‑contact‑resistance surface that prevents galvanic corrosion. An epoxy coating on non‑contact areas adds an additional layer of environmental protection. The integrated M8 stainless steel studs are permanently bonded to the plate, eliminating loose connections.
In heavy‑duty truck electrical systems, corroded or poorly designed connection points are a leading cause of voltage drop, intermittent faults, and premature component failure. The WG9925760004 eliminates these risks by providing a precisely engineered, low‑resistance hub that maintains stable voltage across all critical circuits. Fleet data indicates that using genuine connecting plates reduces electrical‑related downtime by 67% compared to generic terminals or bus bars.
Installation is straightforward: the plate is mounted to the chassis or firewall using the four Ø8.5 mm mounting holes and M8 grade 10.9 bolts torqued to 20 Nm. Battery cables and alternator leads are secured to the M8 studs using lock washers and nuts torqued to 15 Nm. Always clean terminals and apply dielectric grease to prevent corrosion.
Quality control for the WG9925760004 includes 100% dimensional inspection using coordinate measuring machines to verify hole positions, stud alignment, and flatness. Each batch undergoes conductivity testing to confirm >98% IACS. The silver plating thickness is verified with X‑ray fluorescence, and samples are subjected to salt spray testing per ASTM B117 for 720 hours with no corrosion. Only plates that pass these rigorous checks are released for sale.
Environmental responsibility is embedded in the manufacturing process. The copper used contains 85% recycled content, and the silver plating process uses closed‑loop water treatment with zero liquid discharge. Production scrap from stamping is 100% recycled, achieving a 96% material utilization rate. By choosing this genuine component, you support sustainable manufacturing without compromising on performance.
For fleet maintenance operations, the WG9925760004 is available individually in protective polybags or in bulk packs of 10, 25, and 50 units. Each plate is laser‑etched with the OEM part number and batch code for full traceability. Bulk orders are eligible for volume discounts and can be shipped directly from regional distribution centers. The packaging includes installation torque specifications and a QR code linking to a video guide for proper cable termination.
Field performance data collected from over 2,700 SINOTRUK Howo trucks operating in mining, construction, and long‑haul applications demonstrates that the WG9925760004 electrical connecting plate achieves a service life exceeding 1,200,000 kilometers with no reported failures. Fleet managers report that standardizing on this genuine plate has eliminated battery terminal corrosion and alternator output issues, reducing electrical system repairs by 58%.
When ordering, verify that the plate dimensions and stud sizes match your vehicle’s electrical layout. The WG9925760004 is designed for standard SINOTRUK Howo battery and alternator connections with M8 studs and four mounting points. For applications requiring different terminal configurations, refer to the vehicle’s parts manual. Technical support is available through authorized dealer channels to assist with compatibility questions.

During routine maintenance, inspect the WG9925760004 plate for signs of corrosion, discoloration, or loose connections. Replace immediately if any pitting or terminal damage is visible. Check all fasteners for proper torque.
Verify mounting bolt torque at 20 Nm and terminal nut torque at 15 Nm. Re‑torque if any movement is detected. Apply dielectric grease to terminals after cleaning to prevent future corrosion.
Aftermarket electrical connecting plates often use lower‑grade copper or brass with insufficient plating, leading to high resistance, overheating, and rapid corrosion. The genuine WG9925760004 is manufactured from certified oxygen‑free copper with precision silver plating, integrated stainless steel studs, and an epoxy coating that meets SINOTRUK’s durability standards. Counterfeit plates may appear similar but fail under load or corrode, causing voltage drop and electrical fires. With the OEM plate, you receive a fully traceable, conductivity‑tested component engineered for the life of your vehicle.
