As a result, we deliver factory-direct pricing, consistent dielectric quality, and fast delivery. Similarly, this applies to all your switchgear, substation, and electrical safety projects.
In addition, we produce these electrical safety mats to comply with BS921 and IEC 61111:2009 standards. Meanwhile, we offer the full range from Class 0 to Class 4. Therefore, they protect operators from electric shock in low voltage (LV), medium voltage (MV), and high voltage (HV) environments.


Technical Specifications of Electrical Insulating Rubber Mats
To begin with, we manufacture our insulating rubber mats in a full range of classes. Specifically, the table below summarizes the IEC 61111:2009 voltage ratings.
| Class | Max. Working Voltage (AC) | Proof Test Voltage (AC) | Withstand Voltage (AC) | Thickness | Colour Code | Typical Application |
|---|---|---|---|---|---|---|
| Class 0 | 1,000 V | 5,000 V | 10,000 V | 3 mm | Red | LV switchboards, server rooms |
| Class 1 | 7,500 V | 10,000 V | 20,000 V | 4 mm | White | MV switchgear, mining transformers |
| Class 2 | 17,000 V | 20,000 V | 30,000 V | 4.5 mm | Yellow | MV panels, industrial switchgear |
| Class 3 | 26,500 V | 30,000 V | 40,000 V | 5 mm | Green | HV substations, power generation |
| Class 4 | 36,000 V | 40,000 V | 50,000 V | 5.5 mm | Orange | HV transmission, 33kV installations |
Material & Technical Specifications for Electrical Safety Mats
- To begin with, we use high-grade EPDM rubber as the standard base material. This provides excellent dielectric strength for our electrical insulating mats.
- Moreover, we manufacture these ribbed rubber mats to comply with BS921 (tested to 15kV, 650V working voltage) and IEC 61111:2009 (Class 0 to Class 4).
- Additionally, we apply a fine ribbed anti-slip surface pattern on one side. This provides a firmer footing and reduces slip risk near live equipment.
- Furthermore, our switchboard mats are resistant to acid, oil, and UV radiation. They maintain dielectric integrity across a temperature range from -30°C to +80°C.
- For special orders, we supply flame retardant grades and low-emission materials to suit confined or high-risk environments.
- Finally, we offer OEM & ODM — we customize mat thickness, width, length, colour, surface pattern, and packaging according to your specifications.
BS921 & IEC 61111:2009 — Understanding the Standards for Insulating Rubber Mats
In fact, two key standards govern electrical insulating rubber mats in global markets. Furthermore, understanding the difference helps you select the right mat for your project.
To begin with, BS921 is the British Standard for rubber mats for electrical purposes. It covers solid natural or synthetic rubber insulating mats for floor coverage near electrical apparatus with voltages up to 650V r.m.s. to earth. Our BS921 mats are fully certified and tested to 15kV with a recommended safety working voltage of 650V.
Moreover, IEC 61111:2009 is the international standard for electrical insulating matting. It defines five classes (Class 0 to Class 4) based on maximum working voltage. Therefore, Class 0 covers 1,000V and Class 4 covers 36,000V, providing a complete protection range for LV, MV, and HV applications.

How to Install Electrical Insulating Rubber Mats
- First, prepare the floor surface. Ensure the floor is smooth, flat, rigid, and crack-free before laying the mat.
- Then, position the mat. Place the mat directly in front of the electrical installation or switchboard.
- Next, secure the mat. Use recommended adhesive if required, or simply loose-lay the mat for temporary installations.
- After that, inspect the mat. Visually check for damage, cuts, or wear before each use.
- Finally, maintain the mat. Clean with soap and water, and store in a dry environment away from direct sunlight.
Applications & Industries for Electrical Insulating Rubber Mats
- For instance, in LV switchboards, Class 0 mats protect operators working on low voltage control panels and distribution boards.
- Also, in MV switchgear rooms, Class 1 and Class 2 mats provide reliable insulation for medium voltage equipment.
