TEW Cable Applications: Where and Why It Is Used in Canada

In the Canadian electrical industry, TEW (Thermoplastic Equipment Wire) is a widely recognized and trusted wiring solution for internal equipment applications. Designed for durability, flexibility, and compliance with Canadian standards, TEW cable plays an essential role in industrial, commercial, and OEM electrical systems.

This article explores where TEW cable is commonly used and why it remains a preferred choice across Canada.

What Is TEW Cable?

TEW stands for Thermoplastic Equipment Wire. It is typically rated 600V and insulated with flame-retardant PVC. In Canada, TEW wire commonly complies with CSA C22.2 No. 127, ensuring it meets national safety and performance requirements for equipment wiring.

TEW is primarily intended for internal wiring of electrical equipment rather than building distribution systems.

1. Control Panel Wiring

One of the most common applications of TEW cable is in industrial control panels.

Inside control cabinets, TEW is used to connect:

• Circuit breakers

• Relays and contactors

• PLC systems

• Terminal blocks

• Switches and pilot devices

Its flexibility allows for clean routing inside compact enclosures, while its flame-retardant PVC insulation enhances safety.

2. Industrial Machinery

TEW cable is widely used in machinery manufacturing across Canada. It connects internal electrical components in:

• CNC machines

• Packaging equipment

• Conveyor systems

• Automated production lines

Because TEW is rated up to 105°C in many configurations, it performs reliably in demanding industrial environments.
