How to check the home line in the wire with a connector
If you are using a cable that is suitable for direct burial, you do not need a casing. But in the place into the building, should be casing, in order to protect. General steel pipe can be.
Direct protection of the cable in the following ways: cable laying with fine soil or sand cover the cable 100-150mm, the upper brick or cement board cover, the upper and lower layers of the gap is staggered, and then fill the tamping (backfill no miscellaneous And lumps), the protection of the pipe is generally used in the cable crossing, into the ground and the location.
The current scientific means there is no way to check whether there is a circuit breaker on the circuit. In general, in the pipe laying on the line, the tube is not allowed to exist in the wiring, which is to prevent the wiring is not standardized caused by poor contact, and stripping the insulation of the copper wire after long-term use of surface oxidation resistance, resulting in local Serious fever triggers a line fault or accident. In practice, in addition to the provisions of the junction box (including the switch box) within the wiring, in special circumstances also have wiring in the tube, but to strictly enforce the operating procedures, mainly to do the conventional winding, the joints to do tin processing, One can fix the joints to ensure that there is no loosening, the second is to isolate the copper wire with the air. But also to do the insulation package, and finally wrapped with heat shrink tube, so that the treatment of the line connector will not affect the normal use.
Fiber optic connection disk is generally used in the small logarithmic cable connection, connecting the operator communication terminal, the user small room and the use of the client equipment. Optical fiber patch panels are generally used in the operator's room, there are some large customers using fiber for internal integrated wiring may also be used in fiber patch panels, racks are multi-layer fiber optic connection plate combination.
