1. What is armored cable?
1. The outer cover of armored cable is a layer of steel belt as a protective cable, just like wearing armor, so it is called armored cable. Armored cables are made of conductors of different materials and installed in metal sleeves with insulating materials to make a flexible and solid combination.
Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored wires, which are mainly used for temperature detection in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments. Armored thermocouples are a large dose for signal transmission and special heating.
2. What are the precautions for installing cables?
1. When installing cables, it is necessary to ensure that cables and pipelines are installed in parallel, with a distance of two meters, and at least a distance of 0.5 meters when crossing.
2. When installing the cable, the semi-conductive shielding layer must be removed from both ends of the cable terminal. When controlling this semi-conductive shielding layer, be careful and scrape it off gently with a knife to avoid damaging its insulation. Really can’t. We can also polish it with frosted paper.
3. When installing cables, plastic insulated cables and armored cables must be well grounded to prevent three-phase imbalance.
In the process of paying-off, it is not uncommon for the conductor to be damaged due to various reasons, which brings great inconvenience to the construction. The following are the situations and countermeasures that are easy to damage the conductor during tension pay-off:
A wire rubs against the axle car.
Countermeasures: During the pay-off, assign special personnel to take care of the spool car at any time, and stop at any time to change the direction of the spool car or take measures such as cushioning when friction is found.
When the second conductor changes shaft, the snakeskin sleeve is damaged by contact with the conductor.
Countermeasures: Check the quality of the snakeskin case before using it to see if there is any hard object that is easy to scratch the wire, and handle it with care when using it.
Friction between the three wires and the span in the pay-off file during the pay-off process.
Countermeasures: Before the tension setting-out construction, the tension of stringing must be calculated to ensure the distance between the spanning object and the spanning frame. When the calculation can’t guarantee the friction, measures such as lowering the conductor should be taken.
