The 185 cable is not blistered for two meters, can it still be used?

The 185 cable is not blistered for two meters, and it can not be used, and it needs to be tested for insulation, and it can only be used after passing the inspection.

Required tool insulation resistance meter.

Measurement method: 1. First of all, remove the installed cable from other equipment at the connection after full discharge, wipe the cable joint clean, and keep the equipment at a certain safety distance.

2. 1kV megohmmeter for measuring cables of 1kV and below; 2500V megohmmeter for cables above 1kV.

3. Before the telemetry cable is insulated, the low pressure of gas concentration within 10 meters around the roadway must be checked before telemetry.

4. When measuring, the shake table should be flattened first, and the pointer should point to the rated speed when the shake handle is reached, and then reduce the speed, and the positive and negative poles should be shorted with the wire, and the pointer should point to zero, which proves that the shake table is normal.

5. When measuring, the insulation resistance of A, B and C should be measured first, the insulation between A, B and C should be measured, and finally the insulation of the ground wire to the insulating skin should be measured. During the measurement, a special person is arranged at the other end to prevent the cable from contacting or grounding.

6. The rotation speed of the meter shaker handle is about 120r min during telemetry, and the cable resistance value of 15s and 60s is recorded, and the speed of the watch shake should be stable during the telemetry time. Before stopping the telemetry, the connection between the meter line and the cable should be disconnected to prevent the cable from recharging the rocking meter, and the cable core should be discharged to the ground after the measurement.

7. Cable insulation requirements, new cable 1kv and below not less than 50m, 6kv not less than 100m. The insulation of high-voltage cables in operation is generally not less than 50m, and low-voltage cables are generally not less than 2m.

When a whole cable leaves the factory, both ends are covered with heat shrinkable seals to prevent water ingress into the cable during use. Sometimes a coil of cable can not be used up at one time, but also with a head to prevent water from affecting the insulation. The head is made of waterproof glue, and some are heat-shrunken with a high-temperature spray gun.

Hello, very nice to you. It is not universal. To put it bluntly, the head is the end of the bridge, and there is no cable. 100*50 with 50 high head 100*100 with 100 high head.

If the power cable joint is flooded, if it leaks, it will directly cause tripping, and if it does not trip, it will not leak. Therefore, it will not cause harm to people in a short time, but do not touch the cable joint. It should be sent to the power supply bureau and asked a professional electrician to deal with it.

Cable leakage will be sent to the person, should be reported to the relevant management department for processing.

After a long time, the power will be sent to the person and reported to the power department.

injection molding machines; Bar feeders and particle dryers are also required. Second-hand to the local second-hand market should be able to find.

I don't know how it was formed, but I can offer a variety of caps with diameters ranging from 90, 100, 120, 140, 160, and 200.
