Ensuring worker safety in high-voltage environments requires reliable surface protection. Berzelius Performance Materials Inc. manufactures high-quality dielectric rubber insulation mats compliant with IEC 61111:2009 to protect personnel working near live switchboards, control panels, and substations.
Key Voltage Classes & Technical Specifications Selecting the correct insulation mat depends on the maximum operating voltage of your facility. Berzelius offers five standard classes across smooth and fine-ribbed surface finishes:
- Class 0 (BPM-IEC-001): Max Working Voltage: 1.0 kV | Proof Voltage: 5.0 kV | Dielectric Strength: 10.0 kV
- Class 1 (BPM-IEC-002): Max Working Voltage: 7.5 kV | Proof Voltage: 10.0 kV | Dielectric Strength: 20.0 kV
- Class 2 (BPM-IEC-003): Max Working Voltage: 17.0 kV | Proof Voltage: 20.0 kV | Dielectric Strength: 30.0 kV
- Class 3 (BPM-IEC-004): Max Working Voltage: 26.5 kV | Proof Voltage: 30.0 kV | Dielectric Strength: 40.0 kV
- Class 4 (BPM-IEC-005): Max Working Voltage: 36.0 kV | Proof Voltage: 40.0 kV | Dielectric Strength: 50.0 kV
Rugged Performance & Environmental Resistance Formulated from elastomer blends free from insertions, these mats deliver key physical properties:
- Mechanical Strength: Minimum puncture resistance of 70 N and slip resistance >50 N.
- Chemical & Temperature Tolerance: Retains at least 75% mechanical strength during oil and acid resistance tests. Operates safely from -25°C to 55°C.
- Safety Ratings: Flame-retardant properties (does not flame) and certified low-temperature flexibility down to -25°C without cracking or breaking.
Typical Applications
- High-voltage (HT) and low-voltage (LT) control panels
- Transformer, generator, and lift rooms
- Electrical substations and switchboard fronts
- Onsite indoor and outdoor electrical work
Frequently Asked Questions (FAQ)
Q: What standard do Berzelius electrical insulation mats comply with? A: Berzelius insulation mats are engineered and tested in accordance with the IEC 61111:2009 standard for high-quality dielectric rubber.
Q: What maximum working voltage can these mats handle? A: Depending on the class selected, working voltages range from 1.0 kV AC (Class 0) up to 36.0 kV AC (Class 4).
Q: Are these mats resistant to workplace chemicals and extreme temperatures? A: Yes. They maintain at least 75% of their original mechanical puncture resistance after oil and acid exposure tests, with an operating temperature range of -25°C to 55°C.
Q: What surface finishes and sizes are available? A: Mats are available in smooth or fine-ribbed surface finishes. Standard roll widths are 1.0 m and 1.2 m by 10.0 m long, with custom lengths and widths available upon request.
