The silicon tube is a kind of new composite pipe with silica gel solid lubricant.The main raw materials are high-density polyethylene and the core layer is the lowest friction coefficient of the solid lubricant silica gel.Widely used in optical cable communication network system.
Performance characteristics of silicon - core tube
1. The silicon core layer of the inner wall is solid, permanent lubricant, the friction property of the inner wall of the silicon core remains unchanged, and the cable can be repeatedly drawn in the pipe;
2, its inner wall of the silicon core layer is pressed by synchronization in high density polyethylene pipe wall, and evenly distributed throughout the pipe wall, the wall of the silicon core layer and high density polyethylene with the same physical and mechanical properties, not peeling off, out of, and silicon tube with life;
3. The silicon core layer of the inner wall does not react with water, and the pipe can be flushed after the accident.
4. The radius of curvature of silicon tube is small (10 times of its outer diameter).When the tube is in the bend and the gap, it can be determined according to the environment, without any treatment, no need to make a transition;
5. The length of each (disk) silicon tube can be made to any length.In general, the standard length of each (disk) silicon tube is 2000 meters in terms of the convenience of transportation safety and construction.
6. The construction is convenient and the project cost is reduced.The silicone tube is not required to coat the tube, and it can be used directly in the pipe line, without the tube.Since the length of the silicon tube is generally 2,000 meters, the well can be set up every 1,000 meters, and it will only take 15 minutes for each 1000 meters.
Product appearance
High density polyethylene (HDPE) silicon inner and outer walls should be clean and smooth, not allowed to have bubbles, obvious scratches, dents, impurities, color inequity defects.Pipe ends shall be cut flat and perpendicular to the tube axis.The inner wall of silicon core should be tightly welded and no deform phenomenon.The outer wall of the pipe is clearly marked.
Application fields: outdoor communication cable and cable pipeline system, public information network, public transport system, cable network and highway communication engineering construction.

Common fault 1: Check the battery voltage is normal and the grounding resistance measurement is not accurate, the error is large and inaccurate.
Fault reason: This fault is usually caused by the detection signal filtering and the failure of the regulation circuit. The most common cause is the damage of the filter inductor T1.
Remedy: Replace the T1 inductor and fix it immediately.
Common fault 2: Check that the battery voltage is normal, but the ground resistance measurement cannot be performed.
Cause of the fault: This fault may be due to a fault in the switching power supply, AC/DC conversion, and constant current output.
Remedy: Measure the C port with a frequency meter. Without 820Hz AC output, you can gradually check the part of the circuit, from the output transformer, switch, oscillation circuit to find the fault part, replace the new parts can be repaired.
Common fault 3: When the ground resistance tester is used to measure the measurement data, the data is floating, and it is not accurate on time.
Fault reason: This phenomenon "KYORITSU4102A" earth fault resistance tester is usually no fault, the problem is caused by the bad connection between the resistance meter and the earth pile (auxiliary electrode) and the grounding body under test. There are three disconnection wires or loose joints. Causes poor electrical conductivity. If it is found during use that the wire is disconnected from the joint metal plates at both ends, it must be re-welded with solder to ensure proper measurement of the ground resistance tester.
Common fault 4: The head of the grounding resistance tester does not move, or the battery pointer and the grounding resistance tester do not move when measuring the meter head.
Cause of the fault: It may be caused by burnout of the meter header or disconnection of the connection header and the circuit board. This is also due to the excessive vibration of the ground resistance tester during use or transportation.
Remedy: First open the head panel, hand toggle pointer, such as the pointer can not automatically return to zero, indicating that the header has been bad; otherwise it is necessary to weld the header, with a multimeter resistance gauge measurement header, if it is open, It shows that the meter has been burned out. Then use the multimeter's current and voltage to measure the original connection header connector and press the earth resistance meter to check the voltage button. If the multimeter has a voltage indication, it indicates that only the earth resistance tester's fault is caused by the header damage. After replacing the new header, you can repair it. If the header is intact, then open the grounding resistance tester housing and check the header connection. If it is disconnected, it can be done.
Ground Resistance Tester Common Faults
Grounding resistance tester is a commonly used instrument for measuring grounding resistance. It is also an indispensable tool for acceptance inspection of electrical safety inspection and grounding projects. However, there are often minor problems. Common ground fault resistance tester troubleshooting methods are as follows:
