What is UL1145?

An to UL1145

UL1145 is a technical standard that specifies the requirements for wire and cable used in industrial environments. It is developed by Underwriters Laboratories (UL), a global safety certification company. UL1145 covers various aspects including electrical, mechanical, and fire performance characteristics of wire and cable products.

Electrical Requirements of UL1145

In order to meet the UL1145 standard, wires and cables must demonstrate proper electrical properties. This includes factors such as conductor size, insulation resistance, voltage ratings, and current carrying capacity. These requirements ensure that the wire and cable can safely transmit electrical power without causing hazards like short circuits or overheating.

Mechanical Durability

Another important aspect of UL1145 is the mechanical durability of wire and cable products. Wires and cables are often subjected to various stresses in industrial environments, such as bending, twisting, and pulling. UL1145 sets requirements for factors like tensile strength, flexibility, and resistance to physical damage. These standards help to ensure that the wires and cables maintain their integrity even under harsh conditions.

Fire Performance Requirements

UL1145 also includes fire performance requirements for wire and cable products. In industrial settings, the risk of fire can be significant, and it is crucial to use wiring that can resist the spread of flames. The standard covers aspects like flame retardancy, smoke emission, and toxicity of fumes. By adhering to these requirements, UL1145-compliant wires and cables contribute to improved fire safety in industrial applications.
