What are the benefits of polyester electrical cabinet enclosures

Polyester electrical cabinet enclosures are a brilliant choice for protecting sensitive electrics from environmental damage and corrosion. Not only this, but the material is safer, more adaptable, and more economical than other electrical cabinet materials. 

With the option of wall mounted or floor standing cabinets, polyester is a highly recommended material for protecting your electrics.

How polyester electrical cabinet enclosures protect from environmental damage and corrosion

Polyester Cabinet Corrosion Resistance 

Polyester enclosures are inherently resistant to rust and corrosion. Unlike metal enclosures, they do not succumb to oxidation when exposed to moisture or chemicals. This ensures a longer lifespan for your electrical equipment.

Polyester Cabinet Weather Resistance 

Polyester cabinets are built to withstand harsh weather conditions, including rain, snow, and extreme temperatures. They are designed to maintain their structural integrity, even when exposed to the elements for extended periods.

Polyester Cabinet Chemical Resistance

These enclosures are impervious to a wide range of chemicals, making them suitable for industrial environments where corrosive substances are present.

Polyester Cabinet UV Resistance

Many polyester enclosures are UV stabilized, protecting them from the degrading effects of sunlight. This is crucial for outdoor installations.

The Polyester advantages of thermal management


Polyester electrical cabinets excel in thermal management due to their insulating properties, reduced condensation risk, customizable cooling options, energy efficiency, and corrosion resistance. These qualities make them an excellent choice for protecting electrical components while maintaining an optimal operating temperature.

This is because polyester is a natural insulator, which means it helps in maintaining a stable internal temperature. Unlike metal enclosures, which can conduct heat, polyester cabinets do not contribute to heat buildup, ensuring a cooler environment for sensitive electronic components.

In addition, polyester enclosures can be designed with cooling features such as vents and fans, allowing for effective heat dissipation when needed. These features ensure that the cabinet can manage temperature fluctuations efficiently.

Furthermore, Polyester enclosures exhibit lower thermal conductivity, reducing the likelihood of condensation forming on the interior surfaces. This is essential in preventing moisture-related issues, especially in environments with temperature variations.

How a polyester box has such a high resistance to impact


The high resistance to impact of polyester boxes is down to the material’s natural properties, flexibility, molding process, optional reinforcements, and its ability to maintain its performance characteristics across varying temperatures. 

These qualities make polyester boxes a reliable choice for protecting sensitive equipment and components in environments where impacts or mechanical stress are a concern.

The safety advantages of polyester cabinets

The safety advantages of polyester cabinets are an incredibly important factor to consider with electrical cabinets. They offer advanced safety on the following factors:

  • Electrical Insulation. Polyester is an electrical insulator, meaning it doesn’t conduct electricity. This inherent property reduces the risk of electrical shock, especially in cases of equipment malfunction or when working on live circuits inside the cabinet.
  • Corrosion Resistance. Polyester cabinets do not corrode, even in harsh or corrosive environments. This prevents the deterioration of the cabinet’s structural integrity, ensuring it remains a secure enclosure for electrical components.
  • Fire Resistance. Polyester can be manufactured to be flame-retardant, adding an extra layer of safety. In the event of a fire, these cabinets can help contain the flames, reducing the risk of further damage or spreading of the fire.
  • Chemical Resistance. Polyester is resistant to many chemicals, which is crucial in environments where hazardous substances are present. It prevents the cabinets from reacting with or being compromised by these chemicals.
  • Environmental Protection. Polyester cabinets are often designed to be weatherproof and watertight, guarding against environmental factors such as rain and dust, which can damage electrical equipment.
  • Temperature Stability. These cabinets can maintain their structural integrity and safety features across a wide temperature range, ensuring that they remain effective in extreme conditions.

The electromagnetic compatibility of polyester boxes


Polyester electrical boxes have excellent electromagnetic compatibility due to their non-conductive properties. Since polyester is an electrical insulator, it does not interfere with the electromagnetic fields generated by the components inside the enclosure. This prevents electromagnetic interference, making polyester boxes ideal for applications where electromagnetic compatibility is critical. 

Additionally, polyester enclosures can be designed with features like electromagnetic compatibility gaskets and shielding to enhance electromagnetic compatibility, ensuring that sensitive electronic equipment remains protected from any possible interference.

Easily customise your polyester box! 


Customising a polyester electrical cabinet is notably easier compared to metal cabinets. Drilling or cutting into a metal cabinet is complex and risky, as it compromises its corrosion protection and often requires special tools. In contrast, polyester cabinets are much more adaptable and user-friendly. 

Their composition allows for straightforward modification using standard tools, without weakening their corrosion resistance. This ease of customization is a significant advantage, as it simplifies the installation of additional components, cable entry points, or ventilation systems.
