At Quadrangle Products, we are a leading contract manufacturer of wire harnesses and custom cable assemblies, specializing in high-performance solutions for flat-panel displays, embedded motherboards, single-board computers, and their peripherals. With over 30 years of industry experience, we offer custom-designed cable assemblies built to withstand demanding thermal environments without compromising on signal integrity.
Whether you need rapid prototyping with no minimum order quantity (MOQ) in most cases, or full mass-production scaling, our engineering-first team ensures your project is completed quickly, easily, and to the highest industry standards.
High-Temperature Cable Challenges & Engineering
Industrial, medical, military, and aerospace systems frequently face environmental factors that can cause standard cables to fail prematurely. When assemblies are exposed to elevated temperatures, contact with flames, or thermal cycling, selecting the right wire type and insulation is crucial to protect the system and ensure long-term effectiveness.
At Quadrangle Products, our sales team consists entirely of Application Engineers. We work directly with you from initial concept through final production to evaluate environmental stressors—including temperature, abrasion, and weather—and configure the ideal wire type, length, and shielding to fit your exact build criteria.

High-Temperature Wire & Cable FAQs
How does Quadrangle assist with the custom cable design process?
We make the acquisition process as straightforward as possible. Because our engineers act as our sales team, your initial technical inquiry goes straight to an expert. This support is entirely free of charge. We will review your board configurations, display pinouts, and thermal requirements to match you with a turnkey solution.
What specifications should be considered for high-temperature applications?
In addition to the continuous operating temperature, you must consider physical layout constraints, voltage requirements, abrasion resistance, and electromagnetic interference (EMI). We balance these criteria by tailoring the exact jacket material, gauge (12–32 AWG), and shielding style to your system.
Are Quadrangle’s high-temperature cables manufactured to industry standards?
Yes. All of our custom wire harnesses and cable assemblies are manufactured to strict IPC/WHMA-A-620 standards in our ISO 9001:2015 certified facility. We test 100% of our products to eliminate miswiring and ensure total quality before shipment.
Reliable Cables for High-Heat Environments
Don’t settle for standard cables that risk melting or cracking under pressure. Let the engineering team at Quadrangle Products design a precision, high-temperature assembly unique to your hardware requirements.
