High-voltage wiring harness for the oil pump converter of a new-energy bus

UEALINK High-Voltage Wiring Harness for New Energy Bus Oil Pump Converter

Product Overview

The UEALINK high-voltage wiring harness for new energy bus oil pump converters is a complete wiring solution specially designed for commercial vehicles. It strictly complies with the QC/T 29106 automotive standard and provides a comprehensive wiring solution for core components such as pure electric bus oil pumps, battery packs, and on-board chargers. The product features a dual-layer protective structure of fiberglass tubing plus corrugated tubing, effectively resisting harsh operating conditions like engine compartment oil contamination, high temperatures, and vibrations. At the same time, it integrates high-voltage power transmission and low-voltage signal acquisition functions, significantly reducing the number of wires in the entire vehicle and optimizing the overall wiring layout. Before leaving the factory, each unit undergoes 100% full inspection for voltage withstand, continuity, and insulation, ensuring zero open circuits at shipment and providing stable, reliable wiring support for commercial vehicle operation.

Core Components

This product is delivered as a complete wiring solution, including key components such as single-core connectors, EV shielded cables, and copper braided wire harnesses. There’s no need to purchase various wires and connectors separately, thus avoiding issues caused by poor compatibility among different parts. All components are selected and manufactured according to commercial vehicle automotive standards, meeting the high-voltage power transmission and low-voltage signal acquisition requirements of new energy buses. They can be directly applied to the vehicle’s wiring assembly, enabling one-stop delivery and reducing costs associated with coordinating multiple suppliers.

Protective Features

The product adopts a double-layer protection design combining fiberglass tubing and corrugated tubing. This dual-layer structure offers all-round protection against the complex operating conditions inside commercial vehicle engine compartments: the fiberglass tubing boasts excellent high-temperature resistance and insulation properties, isolating the wiring from high-temperature heat sources within the engine bay and preventing cable aging due to heat; meanwhile, the corrugated tubing exhibits outstanding shock resistance and wear resistance, effectively withstanding bumps and vibrations during vehicle operation while also blocking oil contamination from eroding the cables. This dual-layer protection greatly extends the service life of the wiring harness, addressing industry pain points where ordinary harnesses cannot withstand oil contamination or vibration.

Functional Advantages

1. Integrated Design: Combining high-voltage power transmission and low-voltage signal acquisition into one, eliminating the need to separately route high-voltage power lines and low-voltage signal lines. This dramatically reduces the total number of wires in the vehicle, optimizes internal space utilization, and makes the wiring more streamlined and orderly, solving the problem of clutter caused by traditional separate routing.
2. Automotive-Grade Quality: Manufactured in strict compliance with the QC/T 29106 automotive standard, all components meet the rigorous demands of commercial vehicles, stably adapting to the operating conditions of new energy buses and lowering after-sales claim rates.
3. Factory-Inspected Assurance: Each wiring harness undergoes 100% full inspection for voltage withstand, continuity, and insulation before leaving the factory, ensuring no open circuits and meeting insulation performance standards, thereby preventing wiring failures at the source and safeguarding vehicle operational safety.

Core Value

1. One-Stop Complete Delivery: With all necessary wires and connectors included, there’s no need for scattered purchases, reducing multi-supplier coordination processes, cutting procurement communication costs, and improving purchasing efficiency.
2. Simplified Vehicle Wiring: Integrating both high-voltage and low-voltage functions reduces the number of wires and optimizes the overall layout, shortening assembly time and boosting production efficiency.
3. Durable Automotive-Quality: Featuring dual-layer protection combined with automotive-grade standards, this product resists oil contamination, high temperatures, and vibrations, extending its service life and lowering post-sale maintenance costs and claim risks.

Target Customer Groups

Bus manufacturers and new energy construction machinery producers—companies that place high demands on the stability, compliance, and assembly efficiency of commercial vehicle wiring—can find this product’s one-stop delivery, automotive-grade quality, and integrated design perfectly aligned with their production needs.

Application Scenarios

This product is primarily used for complete wiring solutions involving pure electric bus oil pumps, battery packs, and on-board chargers, providing stable high-voltage power transmission and precise low-voltage signal acquisition support for these core components. It meets the whole-vehicle wiring needs of new energy commercial vehicles and can be directly applied during vehicle assembly without additional adjustments.

Solutions to Industry Pain Points

1. Addressing the Pain Point of Scattered Purchases: When buying wires and connectors individually, mismatch issues often arise. This product offers a complete solution, with all components pre-matched and pre-adjusted to ensure compatibility, thus avoiding wiring failures caused by component mismatches.
2. Solving the Problem of Poor Durability in Ordinary Harnesses: Conventional harnesses struggle to withstand engine compartment oil contamination, high temperatures, and vibrations, frequently suffering from aging and damage. The product’s dual-layer protective design effectively handles these harsh conditions, extending the harness’s service life.
3. Tackling Clutter in Whole-Vehicle Wiring: Traditional separate routing of high-voltage and low-voltage lines leads to messy internal wiring and excessive space consumption. The product’s integrated design reduces the number of wires, streamlines the overall layout, and shortens assembly time.
