Product Description

The Single Cable Vertical Flame Testing Machine is designed to evaluate the flame propagation performance of single electrical wires and cables under vertical combustion conditions.

It is widely used to determine the fire resistance and flame-retardant properties of cable insulation materials in accordance with international testing standards. The equipment is suitable for laboratories, cable manufacturers, quality inspection institutes, and certification bodies.

Test Principle

The test sample is mounted vertically and exposed to a controlled flame from a standardized burner for a specified period. The flame application time, burning behavior, and self-extinguishing characteristics of the cable are observed and recorded to assess flame retardant performance.

Application

This vertical flame test equipment is suitable for:

• Electrical wires and cables
• Communication cables
• Insulated conductors
• Low-voltage cable products
• Flame-retardant material testing
