Electrical insulation: secure your systems with our solutions

What is electrical insulation and why is it essential?

L'electrical insulation is an essential function in the design and protection of any electrical or electronic system. 
It consists of prevent the uncontrolled flow of electric current between two conductors or between a conductor and the external environment, using insulating materials. 

In industry, electrical insulation is not just a question of compliance: it guarantees the safety of your equipment. operator safety, protects equipment against failureand ensures the longevity of facilities in demanding conditions. 

There are many issues at stake: 

  • Avoid short circuits
  • Maintaining electrical performance over time
  • Protect components from overvoltage or moisture
  • Ensuring compliance with safety and quality standards 

Good electrical insulation requires rigorous choice of suitable materialsIt can be used in a wide range of applications, depending on voltage, temperature, and chemical or mechanical environments. 

Industrial applications with electrical insulation

Electronics and on-board equipment sector 

  • Protection of printed circuits, connectors, modules and sensors 
  • Prevention of electric arcs, power surges and electrostatics 

Electrical insulation ensures reliability of sensitive cards and componentsThese are increasingly miniaturised environments exposed to thermal and vibratory stresses. 

Energy and electricity distribution sector 

  • Insulation of busbars, transformers and enclosures 
  • Protection against discharge, humidity and condensation 
  • Securing live connections and terminals 

The challenge here is to ensure that constant dielectric strengthEven in the presence of climatic variations, dust or high inductive loads. 

Aerospace, rail, defence 

  • Lightweight insulation complying with fire and smoke standards 
  • Protection against electrostatic interference and discharge (EMI/RFI) 
  • High-performance materials for extreme environments 

These sectors require highly reliable technical insulationThey can withstand thermal cycles, vibrations and extreme altitudes. 

Industrial maintenance and automation 

  • Rapid repair with high-voltage insulating tape 
  • Sheathing or replacement of damaged insulation 
  • Identification and protection of low and high voltage cables 

Solutions must be versatile, easy to apply and durableeven for corrective or preventive maintenance.

FAQ - Electrical insulation

It is a material that prevents the passage of electric current. It is used for protect components, avoid short circuits and ensure user safety. The most common are insulating resins, sheaths, films or tapes. 

Silicone, polyimide (Kapton), PTFE, PVC, polyester, epoxy resin, fibreglass... The choice depends on the voltagethe temperaturethe chemical resistance and mechanical stress. 

La sheath completely envelopes a cable or component. The insulating tape is wrapped around it, allowing localised applicationwhich is often more flexible in terms of maintenance. 

Yes, some formulations (sheaths, tapes, resins) are designed to withstand UV, humidity, weathering and extreme temperaturesThey are therefore suitable for outdoor environments. 

It depends on : 

  • La nominal voltage to be insulated 
  • La operating temperature 
  • L'chemical or mechanical environment 
  • Le type of media (rigid, flexible, mobile)
