Thermocouple Ceramic Insulators Electrical Ceramics Product

Our Thermocouple Ceramic Insulators are precision-engineered electrical ceramics designed for high-temperature and high-voltage applications. Manufactured from high-purity alumina or mullite materials, these insulators provide exceptional thermal stability, dielectric strength, and mechanical durability. They are ideal for protecting thermocouple wires and ensuring accurate temperature readings in extreme environments such as metallurgy, glass, chemical processing, and power generation.

Key Features:

• High-Temperature Resistance: Stable performance at up to 1800°C (varies by material).
• Excellent Electrical Insulation: High dielectric strength for safe and reliable operation.
• Chemical & Corrosion Resistance: Withstands harsh industrial environments.
• Dimensional Precision: Tight tolerances ensure secure wire placement and signal stability.
• Various Hole Configurations: Single-hole, double-hole, triple-hole, and custom bore sizes available.

Typical Applications:

• Thermocouple protection in high-temperature measurement systems
• Electrical insulation in heaters and industrial kilns
• Ceramic spacers for resistance welding and semiconductor processing
• High-voltage insulation components in furnaces and reactors

Material Options:

• 99.7% Alumina (Al₂O₃) – Best for extreme temperatures and electrical insulation
• Mullite – Balanced thermal shock resistance and cost-efficiency
• Steatite – Economical choice for moderate temperature and insulation requirements

Standard Sizes:

• Outer Diameter: 1.0 mm – 10 mm
• Length: 10 mm – 200 mm (customizable)
• Hole Types: Single / Double / Multi-hole (cylindrical or oval)
