What is the difference between an insulating sleeve and a fire jacket?

Mondo Technology Updated on 2024-02-01

Although insulating sleeves and fireproof sleeves are both sleeves used to protect objects such as wires, cables, etc., there are some important differences.

Roles and functions: The insulating sleeve is mainly used to provide electrical insulation, prevent the leakage of current or the intrusion of external current, and ensure that the transmission of current is not disturbed. The main goal of the fireproof sleeve is fireproof, and the use of high-temperature, flame-retardant materials can effectively prevent the spread of flames, provide protection for cables, and prevent fire from causing damage to wires and cables.

Material selection: Insulating sleeves can be made of materials such as plastic, fiberglass, ceramics or polyvinyl chloride, and their choice is mainly based on electrical insulation properties. The fireproof sleeve needs to choose high-temperature, flame-retardant materials, such as high-purity alkali-free glass fiber and silicone.

Temperature range: Fire jackets need to maintain their integrity at extremely high temperatures, typically in the temperature range of -65°C to 260°C and beyond. Although the insulating sleeve also needs to work at a certain temperature, its temperature resistance requirements are relatively low.

Certifications and standards: Fire jackets are usually required to meet specific fire protection standards, such as passing the BS 6853 Flame Retardant Test for Railway Materials, and obtaining the corresponding fire protection certification. Insulating sleeves, on the other hand, need to meet standards and certifications for electrical insulation.

In summary, although insulating sleeves and fireproof sleeves are both sleeves, their focus is to meet different needs: one is electrical insulation, and the other is fire safety.
