What problems should I pay attention to when purchasing intermediate connectors?，

1.When purchasing intermediate joints, special attention should be paid to the quantity and quality of J-30 insulating rubber and semi-conductive tape. The contact area is large, and the standard intermediate connector should be tinned or galvanized.Under the condition of good process control, the sealing and waterproof performance of the shrinkable cable accessories should be better than that of the heat shrinkable cable accessories, and the full content of intermediate joints can be used.

2.When the high-pressure intermediate joint is carried out outdoors, the relative humidity of the air should be 70.In the following, high humidity will increase the ambient temperature or heat the cable.An intermediate joint structure of 100kV should be temporarily constructed.Strictly control the ambient humidity and temperature of 10-30°C to prevent dust and debris from falling.Construction on foggy or rainy days is strictly prohibited.

3.When designing, the cable length requirements should be considered, and intermediate joints should be avoided.When intermediate joints must be used, a fireproof coating or fireproof tape should be applied to the cable connector and adjacent 2-3 meters long cable segments.

4.The intermediate connector of the cable must have higher insulation strength and sufficient mechanical strength to resist the effects of various mechanical stresses and short-circuit currents.The joints should be closed for a long time, not affected by environmental humidity, and have reliable sealing performance.

A liquid-controlled check valve is a valve that relies on controlling fluid pressure to reverse the check valve.This valve has a more important position in the hydraulic support equipment of coal mining machinery.It is a more controlled oil channel with a normal check valve.When the control oil is not connected to the pressure oil, it can act like a normal check valve, and the pressure oil only flows from the oil port to the outlet.Cannot flow in reverse.When there is a control pressure input in the control oil path, the piston rod moves to the right under the pressure oil, and the check valve is opened with the top rod to rotate the inlet and outlet.If the oil change port is larger than the oil port, the oil can flow in reverse.
