High-voltage wiring harness for new energy buses

High-Voltage Wiring Harness for New Energy Buses

Product Overview

The high-voltage wiring harness for new energy buses is a vehicle-grade electrical connection component specially designed for such vehicles, manufactured in strict accordance with the QC/T 29106-2014 automotive industry standard. The product features core characteristics of high-temperature resistance and oil-resistance, while integrating both high-voltage power transmission and low-voltage signal acquisition functions. This effectively reduces the number of wiring harnesses required throughout the vehicle and simplifies the assembly process. Leveraging our proprietary connector and cable integration capabilities, we offer one-stop complete delivery solutions, and can also customize length, wire color, pin configuration, terminals, and other parameters according to customer needs, adapting to various vehicle architectures. Before leaving the factory, each harness undergoes 100% continuity, voltage withstand, and insulation testing, fundamentally preventing issues like short circuits or open circuits, thereby providing stable and reliable electrical connections for new energy buses and related equipment.

Core Performance and Process Characteristics

This product employs vehicle-grade manufacturing processes, with the entire production flow strictly managed in compliance with automotive wiring harness standards. It features a dual-layer protective structure—corrugated tubing and fiberglass tubing—offering not only resistance to oil contamination but also enduring high-temperature environments and vibration impacts during vehicle operation, ensuring stable performance under complex operating conditions. Additionally, the product innovatively integrates high-voltage power transmission and low-voltage signal acquisition into a single unit, breaking away from the limitations of traditional single-function wiring harnesses, significantly reducing the overall number of wiring harnesses needed and streamlining subsequent assembly steps, thus enhancing overall vehicle production efficiency.

Customization and Adaptability

To meet the diverse vehicle architectures and usage requirements of different customers, this product supports multi-dimensional personalized customization, including harness length, wire color, pin layout, terminal types, and more. No additional tooling is required to accommodate differentiated designs, effectively lowering procurement costs and mold investment for customers. This flexible customization approach not only meets the specific needs of new energy buses but can also extend to equipment connectivity scenarios in energy storage, medical, industrial automation, and other fields, providing precise electrical connection solutions for clients across various industries.

One-Stop Delivery Advantage

With our own capabilities in producing connectors and cables, we can deliver complete wiring harness assemblies in a single package. Customers no longer need to separately coordinate with cable suppliers, connector manufacturers, and processing companies, reducing communication and coordination costs among multiple vendors and significantly shortening the overall delivery cycle. Moreover, our unified production and quality control system ensures better compatibility between connectors and cables, minimizing the defect rate caused by mismatched components at the source and enhancing overall product reliability.

Quality Control System

All high-voltage wiring harnesses for new energy buses undergo 100% comprehensive testing before leaving the factory, covering three key areas: continuity testing, voltage withstand testing, and insulation performance testing. Each harness must pass rigorous performance verification to completely eliminate quality issues such as short circuits, open circuits, or poor insulation. Our vehicle-grade production standards and end-to-end quality control ensure excellent vibration resistance, oil resistance, and high-temperature tolerance, effectively reducing the failure rate of vehicle wiring harnesses, lowering subsequent after-sales claim costs for customers, and enhancing the market reputation of end products.

Target Customer Groups

This product primarily targets bus manufacturers, construction machinery companies, energy storage equipment integrators, and medical/industrial automation equipment manufacturers, offering them all-scenario electrical connection solutions—from new energy buses to energy storage, industrial, and medical applications—meeting the demands of various industries for highly reliable, customized wiring harnesses.

Application Scenarios

In the new energy bus sector, the product can be applied to core electrical systems such as oil pump converters and battery pack high-voltage acquisition units, providing stable support for power transmission and signal collection. In the energy storage field, it enables flexible interconnection between storage cabinets, ensuring safe power transmission within the storage system. In industrial and medical settings, it can be used for signal and power transmission inside industrial robots and medical devices, meeting the complex electrical connection needs of advanced equipment. Furthermore, the product’s applicability extends to passenger car high-voltage wiring harnesses, onboard low-voltage acquisition wiring harnesses, copper braided connecting wires for storage cabinets, and other scenarios, providing professional wiring harness solutions for clients across multiple sectors.

Solutions to Industry Pain Points

Addressing numerous current pain points in the industry, this product offers targeted solutions: First, to tackle the issue of poor component matching and high defect rates caused by fragmented procurement of cables and connectors, our one-stop complete delivery model ensures high component compatibility, fundamentally reducing defect rates; second, to address the problem of inadequate vibration resistance and oil resistance due to non-standardized processes—resulting in frequent failures during vehicle operation—the vehicle-grade manufacturing process combined with a dual-layer protective structure significantly enhances the harness’s environmental adaptability, reducing operational failures; third, to solve the challenges posed by multiple vehicle specifications requiring multiple sets of molds, high procurement costs, and long lead times, our flexible customization capabilities eliminate the need for additional tooling, effectively lowering procurement expenses and shortening delivery cycles.
