Xi’An City, ShaanXi Province, China – September 8, 2026 – Hi everyone, This is Xi’an Yingbao Auto Parts Co., Ltd. We are a direct supplier specializing in customized Automotive Connectors and wiring harness assemblies. We provide one-stop professional solutions to solve customers’ customized matching, quality and application problems of automotive connectors and harnesses.

Based on years of industry experience, we found that manufacturers producing heated windshield wipers, cabin heating components and vehicle electric heating parts face the same industry pain point: low-quality connectors and wiring harnesses fail to withstand continuous high temperature. Damaged harnesses and connectors will cause frequent product failure, force manufacturers to change suppliers temporarily, delay production schedules and order deliveries, and damage brand credibility ultimately.

Client Demand: High-temperature Resistance Is The Core Requirement

We recently cooperated with a professional heated wiper manufacturer. The client raised its biggest concern directly: Ordinary low-cost harnesses and connectors adopt inferior insulating materials. Under long-term high-temperature working environment of heated wipers and engine compartments, they will crack, age and short circuit easily. Besides, friction against engine compartment parts, moisture and oil erosion will accelerate wire damage and raise product failure rate greatly.

Frequent supplier replacement, product rework and delayed production bring extra production costs. Therefore, the client’s core demand is clear: purchasing premium high-temperature resistant auto parts with stable performance to reduce after-sales failure rate.

The client’s purchasing list includes: medium-sized high-temperature resistant fuse box with harness, Delphi & Molex original matching connectors. To support our new partner, we offer exclusive first-order benefits: 100pcs sample fuse boxes + 1pc free sample for each type oF Connector for performance testing and on-site verification.

Professional Wire Specification Guide: SAE Standard XLPE Automotive Wire

The client raised a professional and universal question worthy of sharing with all global buyers: What are the differences between XLPE insulated automotive wires: GXL, TXL and SXL? Many overseas buyers only focus on unit price but ignore working condition adaptability, which leads to wire aging and scrappage in high-temperature scenarios. Here is a complete industry guide for your reference.

1. Core Material Introduction: XLPE Cross-linked Polyethylene

GXL, TXL and SXL are all SAE standard automotive wires with XLPE irradiation cross-linked polyethylene insulation. Different from common PVC insulation material, XLPE features high temperature resistance, oil corrosion resistance, anti-aging and flame retardant performance. It is specially developed for harsh engine compartment working conditions, and widely adopted by European & American auto manufacturers for heating component wiring.

Comparison of Common Automotive Wires (Best for Heated Wiper Application)

UL1015 General Wire (Not Recommended for Heating Parts) Advantage: Low procurement cost; Disadvantage: PVC insulation, max temperature resistance 70℃. Poor friction resistance and oil resistance. It will soften and crack rapidly under high temperature. Only suitable for normal-temperature indoor low-voltage circuits, not applicable for heated wiper and engine compartment wiring.

TXL Thin-wall XLPE Automotive Wire (Recommended for This Project) Specification: Heat resistance up to 125℃, thin-wall insulation, small outer diameter, high flexibility; Application: Internal wiring for heated wipers, narrow cabin wiring, gap wiring inside engine compartment. Balanced high-temperature performance and competitive cost, the most cost-effective option for heated wiper assembly.

GXL Medium-wall XLPE Automotive Wire Specification: Heat resistance up to 125℃, thicker insulation wall than TXL, excellent abrasion & scratch resistance; Application: Exposed wiring in engine compartment, wiring with frequent friction contact, projects requiring stronger wear resistance.

SXL Thick-wall XLPE Automotive Wire Specification: Heat resistance up to 125℃, thickest insulation layer, strongest mechanical protection, anti-extrusion and heavy abrasion resistance; Application: Heavy-duty commercial vehicle heating system, exposed wiring with severe friction, extreme harsh engine compartment environment.

Our Service Promise

We will confirm every detail of working condition, temperature requirement and wiring environment before quotation, to match the most suitable harness and connector model for clients. Clear wiring conclusion for heated wiper abrasion demand: If you are troubled by high failure rate of high-temperature wiring harnesses, unstable supplier quality or confusing wire model selection, feel free to contact us. Yingbao team will provide customized professional solutions for your automotive wiring projects.

About us

In the beginning, the trading environment in China was very difficult. I started in the utility room at home with my newborn baby. Two, three, five years, I had my first employee, a 50 square foot office, a store and website for our brand. Until now, we have 50+ employees, separate office buildings and multiple production workshops, working with almost every brand you can see. We use professional technology to solve almost all problems related to auto parts for customers, and YB connectors can be seen by more people.
