What are the mine cable laying installation of construction requirements
what are mine cable laying construction installation requirements? Believe that everybody on this question is also the same meng, then AnWei electric power company of small make up to introduce to you, let's take a look at:
in the baidu search, will be the design and construction of the mine cable laying installation shall be in accordance with the GB 50217 - 94 'electric power cable design code' and other relevant provisions, and USES the necessary cable accessories ( Terminal and connector) 。 Operation quality, safety and reliability of power supply system is not only related to the mine cable itself quality, and also is associated with the construction quality of cable accessories and wiring. Statistical analysis through the line fault, due to factors such as construction, installation and connection failure often than mine cable faults caused by the ontology is much more likely. So to correctly choose mine cable and related accessories, except in accordance with the requirements of specification for the design and construction, should also pay attention to the following several aspects.
1) human laying cable, should be unified command and control the rhythm, every one. 5 - Put 3 m someone shoulder cable, side, slowly.
(2) mechanical casting cable, generally adopts special cable laying machine is equipped with necessary drawing tools, traction, control proper size uniform, so as not to damage the cable.
3. Cable laying installation should be carried out by a qualified professional unit or professionals, and do not conform to the requirements of the relevant rules of construction and installation, could lead to a cable system can not run normally.
4 cast before cable, to check the cable and head are intact appearance, pay attention to the direction of rotation of cable, when casting don't squashed or scratch the cable outer sheath, low temperature in winter when do not break way to straight cable, so as to avoid insulation, sheath craze.
5) cable, such as directly buried must pay attention to the soil condition, general building under the embedding depth of cable should be no less than 0. 3 m, a soft or surrounding environment more complex, such as cultivated land, building construction site or road, it is certain to should have buried depth ( 0. 7 - 1m) , in case of accidental damage from buried cable should be erected sign when necessary.
6. When the bending radius of the cable laying should be greater than the specified value. Before installing the cable laying cable is measured with a 1000 v megohmmeter the insulation resistance between conductors is normal, and according to cable model specifications, length, and temperature of different appropriate revisions to the result of the test 2, small size, Under 10 was solid conductor) Cable should also measure the conductor is on and off.
