What is a single wire and cable vertical combustion testing machine?

In the wire and cable industry, the flame retardant performance of a product is one of the important indicators to measure its safety. The single wire and cable vertical combustion testing machine is a device specially used to test the flame retardant performance of wires and cables in the vertical state. This article will introduce in detail the definition, working principle, application scenarios and related technical parameters of this device.

1. Definition of single wire and cable vertical combustion testing machine

The single wire and cable vertical combustion test machine is a test equipment that simulates the burning behavior of wires and cables when they encounter an open flame in a vertical installation state. Through this equipment, the flame retardant performance of wires and cables can be evaluated to determine whether they comply with relevant industry standards (such as GB/T 18380, IEC 60332, etc.).

2. Working principle

The working principle of this testing machine is to ignite vertically suspended wire and cable samples, observe their burning behavior, and record key data such as burning time and burning length to evaluate their flame retardant properties. The specific steps are as follows:

1. Fix the wire and cable sample vertically on the test frame.

2. Ignite the sample using a standard flame source (such as a methane flame).

3. Observe and record the combustion status of the sample, including whether it is self-extinguishing, the rate of combustion spread, etc.

4. Determine whether the sample meets the flame retardant standards based on the test results.

3. Application scenarios

Single wire and cable vertical combustion testing machine is widely used in the following fields:

1.Wire and cable manufacturer: Used for product quality control to ensure that products meet flame retardant standards.

2.Third-party testing agency: Provide authoritative flame retardant performance testing reports for wire and cable products.

3.Scientific research institutions: Used to study the properties of new flame retardant materials.

4.construction project: Ensure the fire safety of wires and cables used in buildings.

4. Technical parameters

The following are the typical technical parameters of a single wire and cable vertical combustion testing machine:

5. Hot Topics and Hot Content

Recently, hot topics in the wire and cable industry have mainly focused on the following aspects:

1.Flame retardant properties of new energy cables: With the rapid development of the new energy industry, photovoltaic cables, electric vehicle charging cables, etc. have increasingly higher requirements for flame retardant performance.

2.Research and development of new flame retardant materials: Scientific research institutions and enterprises are actively developing more environmentally friendly and efficient flame retardant materials.

3.Updates to international standards: International organizations such as IEC have revised the flame retardant standards for wires and cables, which has attracted widespread attention in the industry.

6. Summary

The single wire and cable vertical combustion testing machine is an indispensable testing equipment in the wire and cable industry. It provides an important guarantee for the safety performance of the product. With the development of the industry, the application scope and testing standards of this equipment will also be continuously updated and improved.
