Electrical Parameters
- Rated Voltage: 24kV, which indicates the voltage level at which the plug - in connector can operate stably for a long - term.
- Rated Current: Usually available in different specifications such as 630A, representing the maximum continuous current that the plug - in connector can carry.
- Power - Frequency Withstand Voltage: It can generally withstand a 1 - minute power - frequency withstand voltage test. The test voltage is much higher than the rated voltage, about 50kV.
- Impulse Withstand Voltage: It can endure a certain amplitude of impulse voltage, such as 125kV and above.
- Partial Discharge: Under 24kV voltage, the partial discharge quantity is usually required to be less than 10pC.
- Grounding Resistance: The grounding resistance of the outer shielding layer is generally required to be less than 1000Ω/cm.
-
Mechanical Parameters
- Insertion and Withdrawal Force: With a proper insertion and withdrawal force design, it ensures easy operation during installation and disassembly while guaranteeing the tightness of the connection. Generally, the insertion force is no more than a certain value (e.g., 200N), and the withdrawal force is not less than a certain value (e.g., 50N).
- Mechanical Life: It can withstand multiple insertion and withdrawal cycles, usually requiring no less than 500 times or even more.
-
Insulation Parameters
- Insulation Resistance: The insulation resistance value is very high, generally greater than 1000MΩ, to ensure good insulation performance and prevent leakage.
- Insulating Material: High - performance insulating materials such as EPDM (Ethylene - Propylene - Diene Monomer) rubber are used, which have good resistance to aging, ozone, and corona.
-
Applicable Cable Parameters
- Cable Specification: The applicable cable cross - section range is usually 25 - 630mm², which can be adapted to cables with different wire diameters.
- Cable Insulation Type: It is suitable for various types of insulated cables such as cross - linked polyethylene (XLPE), polyvinyl chloride (PVC), and ethylene - propylene rubber (EPR).
-
Environmental Parameters
- Operating Temperature Range: Usually, it can operate in the temperature range of - 40ºC to + 80ºC. Some products may have a wider operating temperature range according to different material formulations and designs.
- Humidity Resistance: It has good humidity resistance and can work normally in high - humidity environments. It can usually withstand a relative humidity of up to 95% or more.
- Pollution Degree: It can adapt to different degrees of pollution environments. For example, it can be used in industrial environments with moderate pollution and outdoor environments with general dust.
These parameters are common values for 24kV rear - mounted plug - in connectors. Specific parameters may vary depending on different manufacturers and product models.
