Wire and cable softness tester

 

Principle of operation:

Wire and cable flexibility testers usually use a low-temperature test chamber combined with different test fixtures for testing. Before testing, the desired temperature range and speed are set. Then, the wire or cable sample to be tested is mounted on the test fixture, and a certain bending stress is applied through the test fixture. The samples are kept in the low temperature environment for a certain period of time and then evaluated according to standard specifications.

 

Test Procedure:

Before testing, determine the test temperature and the required test fixture. Mount the wire or cable sample to be tested onto the test fixture and adjust the angle and bending radius of the fixture. Place the test fixture in a low temperature test chamber and set the desired temperature. The sample is kept in the low temperature environment for a certain period of time and then removed for evaluation.

 

Evaluation index:

The Wire and Cable Flexibility Tester mainly evaluates the following performance indexes of wire and cable samples:

1. bending radius: according to the standard specification, to determine the wire and cable in the low temperature required to achieve the bending radius.

2. Breakage and Cracking: Observe whether the wire and cable samples show damage such as breakage, cracking or splitting.

3. strength retention: measure the time for the wire and cable samples to return to their normal state at low temperatures and determine if their strength is affected.

 

Standard Specification:

The testing of wire and cable flexibility testers is generally based on specific international standards such as IEC 60811 (International Electrotechnical Commission standard) or ASTM D2671 (American Society for Testing and Materials standard). These standards regulate test temperatures, test fixtures, evaluation metrics, and qualification requirements for test results.

 

Summary:

The Wire and Cable Flexibility Tester is a device used to measure the flexibility of wires and cables at low temperatures. With this tester, it is possible to assess whether wire and cable materials are soft enough at low temperatures to ensure that they will not break or be damaged during use and installation. The use of this testing machine ensures product quality and improves the durability and reliability of wire and cable.
