What is UL 1072

UL 1072, also known as the Standard for Medium Voltage Power Cables, is a professional technical standard that specifically addresses the performance and construction requirements of medium voltage power cables. This standard was developed by Underwriters Laboratories (UL), a globally recognized independent safety science organization.

Scope and Application

The scope of UL 1072 covers medium voltage power cables with rated voltages ranging from 5 kV to 46 kV. These cables are primarily used in industrial and utility applications to transmit electrical power at medium voltage levels. The standard provides guidelines for the construction, testing, and marking of these cables to ensure their safe and reliable operation.

Requirements and Testing

UL 1072 establishes various requirements for medium voltage power cables, including conductor size and material, insulation thickness, jacketing material, and voltage ratings. The standard also lays down strict criteria for testing the cables to evaluate their electrical, mechanical, and environmental performance, such as withstand voltage, insulation resistance, flexibility, and resistance to heat and chemical exposure.

Benefits and Importance

Compliance with UL 1072 is crucial for manufacturers, suppliers, and end-users of medium voltage power cables. Adhering to this standard ensures that the cables meet industry-accepted safety and performance standards. This helps prevent hazards such as electrical shocks, fires, and equipment failures. Additionally, UL 1072 compliance enhances the credibility and marketability of the cables, as it signifies their quality and reliability.
