Single Conductor Cables, also known as Hook-Up Wire, are widely used in electrical installations and wiring projects. TR16-4-9 is one of the most popular types of single conductor cable. Below this article explains the application field and working principle of this kind of cable.

Application Field

TR16-4-9 is an insulated single conductor cable specially designed for internal wiring in applications with higher temperature requirement. It is mainly used in various kinds of electrical appliances such as industrial machinery control panels, manufacturing and processing industrial equipments, machine tools, lighting equipments, switchgear ventilating systems, generator sets and electrical instrumentations.

TR16-4-9 is also suitable to be used in wet and dry locations, indoors or outdoors for laying in conduits, trunks, ducts, troughs, and any other approved raceways. Due to its fire-retardant PVC insulation, twisted design, large wire size range, and excellent connecting performance, it is trusted and accepted by many professionals and users.

Working Principle

TR16-4-9 features excellent electrical characteristics, including stable current flow, voltage drop, low-electromagnetic interference and high security. The cable is manufactured with a core composed of annealed electrolytic copper strands in twisted construction, which provides a cross-sectional area of 9 mm2 and enables to safely carry 9A current. The insulation layer is composed of a fire-retardant PVC material which enables the cable to withstand temperatures of up to 90°C during operation. It also features excellent connecting performance, ensuring a strong and reliable connection at all times.

Besides, due to its two-layered protection design, it offers superior isolation performance. The outer layers of PVC insulation protect the wires from any short-circuiting hazards while its fire-retardant properties protect the wires from any fire hazard. This provides enhanced safety and protection for the wires.

In conclusion, TR16-4-9 is an excellent single conductor cable which is widely used in various types of electrical appliances due to its excellent electrical characteristics, fire-retardant insulation, strong connecting performance and two-layered protection design, making it ideal for internal wiring in various home and commercial applications.
