Low Temperature Test Chamber for Electric Cables and Cords UL 62

The Wewon’s low temperature test chamber complies with the test standards of GB2951.4, UL62, IEC540, and IEC 60598-2-21. When selecting a low-temp test chamber, one of the most important features to consider is the available control functions and programming languages. Look for test chambers with advanced digital temperature controllers that offer high-end features like synchronization between devices, automated protocol execution and pre-programed testing procedures from manufacturers.

Also, make sure the software and languages used are compatible with your organization’s existing IT infrastructure. This ensures proper data collection for your tests and conforms with applicable industry standards. The low temperature test chamber is suitable for the winding resistance of wires and cables in low temperature environments. The tested wires and cables are wound in different diameters in a specific low temperature environment to check whether there are cracks and other defects on the surface.

The specific test method is: first set the test room’s temperature, when the temperature reaches the set value, take a sample of a certain length and put it into the low temp chamber’s test room, after the test time is up, immediately wind it around the specified diameter at a uniform speed Then take out the sample and check whether there are cracks or cracks on the surface. If your test conditions need to be customized, Please explain them to our customer service in the email. The purpose of this is to avoid misunderstandings!

Low-temperature test chambers are designed specifically to test the performance and safety of electric cables and cords. When choosing the right low-temperature test chamber for electric cables and cords, you must consider not just performance, but also environmental issues. It is important to check the type of refrigerants used in order to assess the green-friendliness of your device. You’ll want to select a system that is as efficient as possible to help minimize any potential environmental impact and keep your cost of ownership low.

It is critical to run pre-testing of components when looking for the right Low Temperature Test Chamber solution. Pre-testing allows you to assess how components and assemblies will react under extreme cold conditions, while ensuring accuracy and reliability of test results. This helps ensure any potential errors or malfunctions that can occur at higher temperatures are eliminated or kept to an absolute minimum. Additionally, pre-testing of components allows technicians use the results for determining safe handling procedures for materials exposed to low temperatures.

Low temperature chambers are specifically designed for extended operations in low-temperature environments. It is important to select temp test chambers with durable materials and corrosion protection. Quality tested chamber solutions should include high-grade Stainless Steel components, combination of rust resistant liners such as anodized carbon steel or stainless steel and other rust blocking efforts to ensure the efficiency of your equipment over time. Additionally look for insulated exterior walls with energy efficient foams and materials to maintain temperature accuracy and stability.

A cold temperature test chamber is essential to ensure electric cables and cords and processes perform reliably across a wide range of temperatures. When selecting a low temp chamber, keep in mind the features, safety protocols, and durability needed to protect against extreme temperatures. Additionally, take into consideration safety protocols, rapid cooling technology, insulation of the chamber walls, and durability of the materials used in order to maximize performance and ensure protection against extreme temperatures.


Impact Test Apparatus In the Low Temperature Test Chamber → The impact test apparatus should be used in conjunction with the low-temperature box, and the fixture should be placed on a sponge rubber pad with a thickness of about 40mm. It should be placed in a suitable low-temperature box before and during the test. Drop impact height: adjustable from 10 to 250mm. The impact test apparatus is suitable for impact tests on plugs, sockets, switches, screw glands, covers, wires and cables, and electrical conduits. After the test, Wipe off the water droplets on the surface and place it in a ventilated and dry place.
