Double Silicone Insulated Cables feature two layers of silicone insulation, offering exceptional thermal and electrical properties. These cables are renowned for their flexibility, resistance to high temperatures, and suitability for demanding environments.
Operating Temperature: -60°C to +180°C
Operating Voltage: 3/500 V
Insulation: silicone rubber
Approval: EN 60332-1-2 / IEC 60332-1-2
The innermost layer of silicone insulation directly surrounds the conductor. This primary insulation layer serves as the primary electrical barrier, preventing electrical current from escaping the conductor and ensuring safe transmission of power or signals.
Key Features:
High Dielectric Strength: Provides excellent electrical insulation properties, maintaining high dielectric strength to withstand voltage stress.
Thermal Resistance: Offers resistance to high temperatures, typically ranging from -50°C to 200°C or higher, depending on the silicone formulation.
Flexibility: Maintains flexibility and pliability, allowing the cable to bend and flex without cracking or compromising insulation integrity.
The outer layer of silicone insulation surrounds the primary insulation layer and provides additional mechanical protection, environmental resistance, and insulation properties.
Key Features:
Mechanical Protection: Offers protection against abrasion, impact, and physical damage, extending the cable's service life in rugged environments.
Chemical Resistance: Resistant to oils, solvents, chemicals, and moisture, enhancing the cable's durability in harsh industrial or outdoor settings.
UV and Weather Resistance: Withstands exposure to UV radiation and weather conditions without degradation, ensuring long-term reliability.
Enhanced Flexibility: Maintains cable flexibility and ease of handling, even in cold temperatures or tight spaces.
Temperature Resistance:
Double silicone insulated cables can withstand much higher temperatures (typically up to 200°C or more) compared to PVC insulated cables, which have lower temperature ratings (usually up to 70°C or 90°C).
Flexibility and Durability:
Silicone insulation offers superior flexibility and durability over a wider range of temperatures compared to PVC, which can become brittle at low temperatures.
Environmental Resistance:
Silicone rubber provides better resistance to moisture, chemicals, oils, UV radiation, and environmental factors compared to PVC, making double silicone insulated cables suitable for harsh environments.
Electrical Performance:
Silicone insulation has excellent electrical properties, including high dielectric strength and low dielectric constant, which can be superior to PVC insulation in certain applications.
Temperature Resistance:
Both double silicone insulated cables and XLPE insulated cables have high-temperature ratings, but silicone rubber can withstand higher continuous operating temperatures.
Flexibility and Mechanical Properties:
Silicone insulation maintains flexibility and elasticity over a wider range of temperatures compared to XLPE, which can become stiff at low temperatures.
Chemical and Environmental Resistance:
Silicone rubber offers superior resistance to chemicals, oils, and environmental factors compared to XLPE, making it more suitable for outdoor and industrial applications.
Installation and Handling:
Silicone insulated cables are generally easier to handle and install due to their flexibility and pliability compared to XLPE, which may require more care during installation.
Temperature Resistance:
Both double silicone insulated cables and Teflon insulated cables have high-temperature resistance, but Teflon can withstand extremely high temperatures (up to 260°C) compared to silicone.
Flexibility and Handling:
Silicone rubber is more flexible and easier to handle than Teflon, which can be stiff and less compliant.
Cost and Availability:
Silicone insulated cables are generally more cost-effective and widely available compared to Teflon, which can be more expensive and specialized.
Chemical Compatibility:
Teflon has exceptional chemical resistance, often surpassing silicone rubber in certain aggressive chemical environments.
Temperature Range:
Both silicone and rubber insulated cables offer wide temperature ranges, but silicone has better high-temperature performance and stability.
Environmental Resistance:
Silicone rubber provides superior resistance to UV radiation, ozone, and outdoor exposure compared to standard rubber insulation.
Electrical Properties:
Silicone rubber generally has better electrical properties, including higher dielectric strength and lower dielectric constant, compared to standard rubber insulation.
