7.5Ω 2 Conductor MgO Insulation Alloy 825 XMI-A32 MI Series 300V Heating Cable

Allowable Ampacity for 7.5Ω 2 Conductor MgO Insulation Alloy 825 XMI-A32 MI Series 300V Heating Cable: 100 Amps

About:

This heating cable features a resistance of 7.5Ω, which is indicative of its power output and heating efficiency. It utilizes two conductors, enhancing its reliability and effectiveness in heat distribution. The cable operates at a lower voltage of 300V compared to some higher voltage models, making it suitable for applications where lower voltage supply is either sufficient or a necessity.

Also Known As:

The XMI-A32 model may be referred to by various names that highlight its key features or applications. It could be known as "dual-conductor mineral insulated heating cable" or "low voltage Alloy 825 heating cable," emphasizing its structure and material composition.

Application:

• Building and construction: Provides underfloor or in-wall heating to maintain comfortable indoor temperatures and prevent pipe freezing.
• Process temperature maintenance: Used in industrial or manufacturing settings where maintaining specific process temperatures is critical for material handling or chemical reactions.
• Frost protection: Ideal for use in environments prone to freezing temperatures, safeguarding infrastructure components like pipes and roofs.

Standards:

• Compliance with electrical safety codes.
• Certification for use in hazardous or explosive environments, if applicable.
• Quality standards ensuring resistance to environmental stresses and operational longevity.

Construction:

• Conductor: Incorporates two conductors made of Alloy 825, known for excellent mechanical and corrosion resistance properties.
• Insulation: Utilizes Magnesium Oxide (MgO) for high electrical insulation and effective heat transfer.
• Sheathing: A robust outer sheath protects the internal components, enhancing the cable's durability and environmental resistance.
• Voltage Rating: Specifically designed for 300V applications, suitable for a range of environments and power systems.

Features:

• Reliable during long life: 10 year product warranty available, robust and rugged construction, proven in harsh climates extends life expectancy
• Reduced total installed cost
• Dual conductor versions particularly suited to small pipes and instrument tubing
