Product Description

Type KCA 2*0.71 Thermocouple Cable with Fiberglass Insulation

Product Overview

The Type KCA 2*0.71 thermocouple cable, expertly crafted by Huona New Material, is engineered to meet the demands of precise temperature measurement across a diverse range of industrial applications. Uniquely, its conductors are composed of Iron-Constantan22, with each conductor having a diameter of 0.71mm. This specific alloy combination, paired with high-quality fiberglass insulation in distinct red and yellow colors, offers a reliable and cost-effective solution for temperature sensing setups.

Standard Designations

  • Thermocouple Type: KCA (specifically designed as a compensating cable for Type K thermocouples)
  • Conductor Specification: 2*0.71mm, featuring Iron-Constantan22 conductors
  • Insulation Standard: Fiberglass insulation adheres to IEC 60751 and ASTM D2307 standards
  • Manufacturer: Huona New Material, operating under strict ISO 9001 quality management system

Key Advantages

  • Cost-Effective Precision: The Iron-Constantan22 conductors provide a more budget-friendly option compared to some traditional thermocouple alloys, without sacrificing performance within the standard application temperature range. This makes it an excellent choice for large-scale installations where cost control is crucial.
  • High-Temperature Resilience: Thanks to the fiberglass insulation, the cable can operate continuously in temperatures ranging from -60°C to 450°C and withstand short-term exposure up to 550°C. This far exceeds the capabilities of common insulation materials like PVC (usually limited to ≤80°C) and silicone (≤200°C), making it suitable for harsh, high-temperature industrial environments.
  • Durability and Longevity: The fiberglass braid offers robust resistance to abrasion, chemical corrosion, and thermal aging. This ensures that the cable maintains its integrity and performance over an extended service life, even when subjected to the rigors of industrial settings.
  • Flame-Retardant and Safe: Fiberglass is inherently flame-retardant with low smoke emission properties. This makes the Type KCA 2*0.71 cable a safe choice for applications in high-risk environments where fire safety is a top priority.
  • Efficient Signal Transmission: The 0.71mm Iron-Constantan22 conductors are optimized to minimize signal loss, ensuring a stable and accurate thermoelectric output. The red and yellow insulation colors also aid in easy identification and proper connection during installation.
