What is Deionized ultra-high voltage cable test water termination system

Dec 30, 2024Leave a message

For cross-linked cables of 110kV and above, during the test process, the test conditions must be

Looking for a very versatile oil and water terminal, because its application principle is to enhance the insulation level of the medium, and increase the breakdown field strength, but only increasing the breakdown field strength cannot meet the test requirements. The deionized water is terminated and the deionized water is used for even distribution to meet the test requirements.

Based on absorbing advanced foreign technology and combining many years of domestic on-site experience and qualifications, the company CTS-series water terminal system, the system consists of a deionized water treatment unit and two water terminations system, with one end being the proximal end and the other end being the far end. (The design specifications and dimensions of two terminals are one)

due to interchangeable testing)

Standard:

GB/T22078-2008

IEC62067-2011

 

Working condition

Operating temperature: 0-40℃

Storage temperature: -5~50℃

Relative humidity: ≤80%

Environmental conditions: No serious pollution

Altitude: ≤800m

 

Function

Cable dielectric loss test

During the test, the length of the cable inside the pressure balancing ring is 5.5 meters, and the excluding shield needs to be stripped for 6 meters.

 

Features

The number of water terminals is two, and the two are completely similar and can be exchanged at will.

The water terminal can meet the requirements of local discharge of AC-350kV voltage class cables, and the test voltage is the highest in the process 580kV, in the above test process, the water terminal meets the invisible discharge of the background of the demander's equipment.

The water terminal can meet the requirements of AC-350kV voltage grade cable voltage test and can meet the requirements of 350kV continuous 30 days of use.

The water terminal can meet the requirements of dielectric loss measurement for AC-350kV voltage class cables and can have a connection protection ring. Retractable measuring rod for easy grounding of the protection ring on the terminal inner cable body. A picture should be provided to show the design style of the part.

The water terminal can meet the requirements of the lightning shock test of AC-350kV voltage class cable, not 1000kV Flashover, no breakdown.

In the process of terminal use, the water can have a good electric field uniform effect on the cable outer screen fracture, and avoid the impact at the fracture.
