As one of the key standards for medium voltage power cables in North America, UL 1072 establishes stringent requirements for cable design, manufacturing, and performance testing. Products certified to this standard represent not only compliance with market requirements, but also a commitment to high-quality and reliable power transmission solutions.

SUNKEAN's medium voltage cable products have officially achieved UL 1072 certification, marking a significant milestone in our journey toward serving the North American utility-grade power infrastructure market — earning the industry's "silent vote of trust."

UL 1072-certified cable series are designed for rated voltages from 5 kV to 35 kV, covering a wide range of applications — from internal industrial power distribution networks to collector systems in large-scale wind and solar power plants.

To meet different system grounding configurations and insulation coordination requirements, the UL 1072 series is available with 100% and 133% insulation levels. This allows engineers to select the optimal solution based on system conditions and overvoltage requirements, achieving the best balance between safety, reliability, and cost efficiency.

The product range offers 90°C and 105°C operating temperature ratings to meet different application requirements and environmental conditions.

Conductor sizes range from 2 AWG to 1500 kcmil, providing flexible options for various current-carrying requirements. The insulation shielding layer features an easy-strip design, simplifying termination and jointing processes during installation.

Depending on the temperature rating, the outer jacket can be supplied in XLPE or LLDPE materials, offering excellent UV resistance and weather durability for long-term outdoor exposure without the need for additional protection.

Renewable Energy (Wind & Solar Power)

In wind farms and utility-scale solar plants, 35 kV collector circuits require cables capable of withstanding temperature fluctuations, UV exposure, and long-term outdoor operation. The superior water resistance, weatherability, and electrical stability of TR-XLPE insulation ensure reliable power transmission from generation units to substations.

Heavy Industry & Manufacturing Facilities

Industries such as metallurgy, paper manufacturing, and chemical processing rely on medium voltage cables for motor feeders and primary distribution networks. 5 kV and 15 kV cables are commonly used in these applications, while the 105°C temperature rating provides additional safety margins under overload conditions.

Data Centers & Critical Infrastructure

Large-scale data centers typically utilize 15 kV medium voltage cables for dual power supply systems. These cables provide highly reliable power delivery while supporting the stringent safety and reliability requirements of critical infrastructure.

Outdoor, Overhead & Direct Burial Installations

With sunlight-resistant jackets, UL 1072 cables can be installed in outdoor cable trays or exposed environments for long-term operation. Optional armoring provides additional protection against moisture ingress and mechanical stress in direct burial applications.

More Than a Certification — A Commitment to Reliability

The UL 1072 certification is a key milestone that enables SUNKEAN to enter North America's core medium voltage power infrastructure market.

But beyond the certification itself, what matters most is our commitment to delivering dependable performance at every critical connection point where systems are expected to operate safely and continuously for decades.

At SUNKEAN, reliability is not just a specification on paper — it is embedded into our materials, engineering, manufacturing processes, and every cable we deliver.
