Constant Temperature and Humidity Test Chamber for Wires and Cables

Wire and Cable Constant Temperature and Humidity Test Chamber is a specialized device used to test the performance of wires and cables under various environmental conditions. Below is a detailed introduction to this equipment:

I. Purpose

Primarily used to test the heat resistance, cold resistance, dryness resistance, humidity resistance, and other properties of wires and cables, as well as to evaluate key indicators such as electrical performance, mechanical performance, and thermal performance under different temperature and humidity conditions. By simulating various environmental conditions such as high temperature and high humidity, high temperature and low humidity, low temperature and high humidity, high temperature, and low temperature, it enables a comprehensive and accurate assessment of wire and cable performance.

II. Features

High-Precision Control: Utilizes highly stable temperature-sensing resistors and an advanced temperature and humidity control system to ensure precise control of temperature and humidity within the set range.

Large Capacity Design: The interior space of the test chamber is spacious, accommodating the storage and testing needs of wires and cables of various specifications.

Automated Operation: Equipped with an LCD touch screen and a programmable controller, allowing users to easily set test parameters and monitor the testing process in real time.

Multiple Protection Functions: Includes various safety devices such as a power leakage protector, dry-burn protection device, and water system protection device to ensure the safety and reliability of the testing process.

III. Technical Parameters

Internal Dimensions: Vary depending on the specific model, generally large to accommodate testing of wires and cables of different specifications.

External Dimensions: Also vary depending on the specific model but are typically larger than the internal dimensions to accommodate insulation layers and control systems.

Temperature and Humidity Adjustment Method: Employs a balanced temperature and humidity adjustment method (BTHC), achieving precise control through PID intelligent regulation.

Temperature Range: Typically adjustable between -70°C to 150°C, meeting various testing needs.

Humidity Range: Typically adjustable between 20% to 98% RH, simulating different humidity environments.

Temperature and Humidity Control Accuracy: Generally up to ±0.2°C and ±2.5% RH, ensuring the accuracy of test results.

IV. Operating Methods

Appearance Check: Ensure the test chamber shows no signs of damage or deformation.

Internal Cleaning: Inspect and clean the interior of the test chamber to ensure it is free of debris and dust.

Power Cord Check: Confirm that the power cord and plug are intact.

Placement: Position the test chamber on a stable surface with no obstructions around to facilitate heat dissipation.

Power Connection: Plug in the power cord and turn on the power switch; the device should enter standby mode.

Startup Self-Test: Press the startup button to perform a self-test and check if all parameters are normal.

Parameter Setting: Set the required temperature and humidity values according to the test requirements.

Start Test: Press the start button to begin the test and monitor the process in real time.

Stop Operation: Press the stop button to halt the operation once the test is complete.

Power Off: Turn off the power switch, unplug the power cord, and clean any debris and dust from the interior and exterior of the test chamber.

V. Application Areas

Wire and Cable Constant Temperature and Humidity Test Chamber is widely used in industries such as electronics, electrical appliances, communications, military, plastics, hardware, and chemicals. It is particularly suitable for virtual climate environment testing of products like wires and cables, electronic components, and automotive parts.
