Wire and cable are a major part of a wide range of applications, from simple appliance wiring to major manufacturing facilities. For this blog, we'll be breaking down the different products that are utilized in demanding electrical environments. We'll also be explaining the differences in shelf life, reliability, resistance and many other important application factors to consider.

Hazardous Work Environments

Wire & Cable: Harsh Environments

Electrical wire and cable are subject to a number of different difficult work environments, in a wide selection of different industries. Some of these complex environments that applications are often subject to include:

  • Manufacturing Environments
  • Laboratories
  • Environmental Weathering
  • Aerospace Applications
  • Marine Environments
  • Military Applications
  • Oil and Gas Industry


Why is it necessary to choose the correct product for a specific application?

Applications are unique by nature, whether it be the application itself, the geographical location, or some other unique aspect. These defining traits are the fundamental guidelines for selecting the perfect electrical solution. The more popular types of applications have what is known as a "certification", which has been put in place in order to get a consistently safe end-results. For example, CSA FT4 is certified for installation in building risers and residential environments, where the different wire routes aren't within general air handling plenum spaces. These types of certifications are an extremely important part of the industry, as they provide guidelines for potentially dangerous applications. 

Choosing the Correct Type of Cable


Advantages of Extreme Environmental Cable

Choosing the correct cable and specific construction is essential in every application, while additional attention is typically required for the more demanding settings. If a wire or cable were to fail, the system it's supporting would ultimately fail as well; therefore, cables installed in difficult environments require significantly more resistance in order to keep the application working consistently and reliably. The different cabling advantages are a subsequent result of the construction type selected. The wide selection of different constructions also typically allows the end consumer to have multiple construction alternatives for the application—for example, CSA AWM, UL1213 or M16878/4, Type E


In these different environments, the cable chosen as a harsh application solution may be subject to:

  • Shock
  • Temperature Fluctuations
  • Chemicals
  • Weathering
  • Moisture
  • Abrasion
  • Continuous Bending

A common way of identifying workplace hazards is to classify them into various categories:

  • Biological: These include viruses, bacteria, animals, plants, insects and also humans.
  • Chemical: These include various chemicals, liquids and solvents. The hazard associated with them depends on their physical properties and whether they are toxic, irritants, corrosives or mutagens.
  • Mechanical: The hazards caused by the moving parts of machinery, plants or a piece of equipment.
