Product Description

Type K Thermocouple Cable (2*0.8mm) with 800℃ Fiberglass Insulation & Sheath

Product Overview

The Type K thermocouple cable (2*0.8mm) from Huona New Material is a specialized high-temperature temperature-sensing solution engineered for extreme industrial environments. It features two 0.8mm diameter core conductors (Chromel for positive, Alumel for negative)—the signature alloy pair of Type K thermocouples—with dual-layer protection: individual conductors insulated by 800℃-rated fiberglass, plus an overall 800℃ fiberglass sheath. This double fiberglass structure, combined with Huona’s precision manufacturing, delivers unmatched heat resistance, signal stability, and durability, making it the top choice for ultra-high-temperature measurement scenarios where standard insulation (silicone, PVC) fails.

Standard Designations

Thermocouple Type: K (Chromel-Alumel)
Conductor Specification: 2*0.8mm (two 0.8mm diameter thermocouple alloy conductors)
Insulation/Sheath Standard: Fiberglass complies with IEC 60751 and ASTM D2307; rated for 800℃ continuous use
Manufacturer: Huona New Material, certified to ISO 9001 and IECEx for hazardous/high-temperature applications

Key Advantages (vs. Standard Type K Cables)

This cable outperforms conventional Type K cables with lower-temperature insulation in three critical areas:

Extreme Heat Resistance: 800℃ continuous operating temperature (short-term up to 900℃ for 1 hour)—far exceeding silicone-insulated cables (≤200℃) and standard fiberglass (≤450℃)—enabling use in near-flame environments.
Dual-Layer Durability: Individual fiberglass insulation (for conductor isolation) + overall fiberglass sheath (for mechanical protection) doubles resistance to abrasion, chemical corrosion, and thermal aging; service life 3x longer than single-insulation cables.
Uncompromised Signal Accuracy: 0.8mm Chromel-Alumel conductors minimize signal attenuation, maintaining Type K’s standard thermoelectric output (41.277mV at 1000℃ vs. 0℃ reference) even at 800℃, with drift <0.1% after 500 hours of high-heat operation.
Enhanced Safety: Inherently flame-retardant (UL 94 V-0 rating), non-toxic, and low-smoke—safe for use in enclosed industrial spaces (e.g., furnaces, boilers) where fire risk is high.

Typical Applications

High-Temperature Furnaces: Continuous temperature monitoring in ceramic sintering furnaces, metal heat-treatment furnaces (carburizing, annealing) operating at 700-800℃.
Metal Smelting: Measuring molten metal temperatures in foundries, particularly for cast iron and steel production (near tapping points).
Waste Incineration: Monitoring flue gas and combustion chamber temperatures in municipal solid waste incinerators.
Aerospace Testing: Thermal profiling of jet engine components and rocket nozzle test benches during high-heat trials.
Glass Manufacturing: Controlling temperatures in float glass annealing lehrs and fiberglass melting furnaces.

Huona New Material subjects every batch of this Type K cable to strict quality testing: thermal cycle tests (100 cycles of -60℃ to 800℃), insulation breakdown checks, and thermoelectric stability verification. Free samples (1m length) and detailed technical datasheets (including EMF vs. temperature curves) are available upon request. Our technical team provides tailored guidance—such as connector matching for high-temperature joints and installation best practices—to ensure optimal performance in extreme environments.
