- Commodity name: Mica tube
Excellent Electrical Insulation Performance ：With a dielectric strength of 15-30kV/mm, it can effectively insulate wires and rods in low-voltage to high-voltage (1kV-50kV) systems, preventing short circuits and arcing.
Extremely High Temperature Resistance ：Can withstand continuous operating temperatures of 400°C to 1000°C (depending on the mica type), maintaining stability in high-temperature environments such as furnace heating elements and engine compartments.
Structural Durability ：Robust and lightweight, with high tensile strength (≥20MPa), it can resist deformation caused by mechanical stress or vibration, ensuring long-term protection of the enclosed components.
Flame Retardancy ：Classified as non-combustible material, with a UL94 V-0 rating, it is flame retardant and does not release toxic fumes, enhancing the safety of enclosed electrical systems.
Chemical and Moisture Resistance ：Resistant to oil, weak acids, and alkali corrosion, with a moisture absorption rate ≤1.0%, ensuring performance in humid or industrial environments.
Multifunctional Adaptability ：Available in various diameters and lengths, with a smooth inner wall, wires or rods can be easily inserted without damaging the insulation layer.
Specifications
Inner Diameter ：3mm-100mm, customizable to accommodate different sizes of wires, heating elements, or mechanical rods.
Wall Thickness ：0.5mm-5mm, balancing insulation performance and structural strength to meet the needs of specific applications.
Length ：Standard length is 50mm-1000mm, custom lengths are available for large industrial equipment.
Material Composition ：Options include white mica (suitable for moderate temperatures up to 600°C), phlogopite (suitable for high temperatures up to 800°C), and synthetic mica (suitable for extreme temperatures up to 1000°C).
Application Areas
Motors and Generators ：Used to insulate rotors and stator bars, protecting them from high temperatures and electrical interference within the motor housing.
Industrial Furnaces ：Wraps heating elements, thermocouples, and sensor wires, protecting them from direct heat and ensuring accurate temperature measurement.
Household Appliances ：Insulates heating rods in ovens, toasters, and industrial heaters, preventing heat transfer to surrounding components and improving energy efficiency.
High-Voltage Equipment ：Sleeves high-voltage cables and busbars in transformers and switchgear, providing additional insulation and reducing the risk of electrical leakage.
