A special place in the arrangement, or suburban areacountry house occupies a strip of electrical communications. To properly lay the cable in the ground, it is necessary to know the features of the site, to strictly adhere to safety rules and regulations.
Laying cable communications is not as simple as it may seem to a person are not privy to the details.
First of all, it should outline the route forcabling. It should not be placed near trees. It is undesirable to allow the cable crossing with other underground electrical networks. Also avoid crossing areas where usually increased load on the ground.
Proceed to digging trenches. Its depth should not be less than 70 cm. Dig a trench clear of objects that could damage the cable sheath. Remove stones, glass and metal objects.
Prepare a sandy base. Suitable easiest quarry sand. Sand has to fill the bottom of the trench to a height of at least 10 cm.
Prepare cable. Carefully check the integrity of the outer shell. The observed damage repair on site or replace cable. Check the insulation tester is carried out with a conventional ohmmeter. Check the insulation of cable cores together.
Before laying on the slide cable tube (cases), which will be protected from damage. This usually requires at the intersection with the tracks at the entrance of cars, etc.
Proceed with the installation of the cable in a trench. When laying necessarily contemplate the slack, cable It should not be stretched. It would be better if cable It will be laid with a twisting, undulating.
Make a plan for passing your underground utilities, tying the distance to the cable of fixed items, structural elements of buildings and outbuildings.
Now cable should fill with sand (about 10 cm bed)then add a layer of soil thickness of 15 cm. Tamp the soil down. Then route the signal band, it should be over the cable all over the track. Fill the trench completely, making a small hill in the event of ground subsidence.
Finally, check the insulation resistanceinstalled cable. If the detected fault, all the work will have to remodel again. If the tester shows that everything is in order, you can proceed to the installation of an electrical circuit.
