Q:What brand of cable is good, what are the top ten brands of wires?

Power circuit box, the home of the circuit is divided into lighting, walls, air conditioning, etc., there is the bathroom and the kitchen line and the separation of the room.

Q:If you want to sell wire and cable, then what to do in advance to detect? The The The The The

Line width, and can not pass the gap between the chip pins, even after, but also because the distance between the wire and the lead is less than the electrical rules specified in the safe distance. In general, the ground can not pass through the gap between the chip pins, go outside or take the gap between the two columns through the gap. The width of the ground wire can also be set appropriately, and the wire is widened by adding a polygon brass cut. The safety distance in the electrical rules defaults to 10 mils, which is relatively small, and the safety distance of the different networks should be set separately as needed.

Q:Ipad not charge how the matter. Said the cable or accessories have not been certified, and may not be able to cooperate with this ipad reliable work....

Then you get the repair station to see what is the problem

Q:How to determine how much wire and cable should be used, the current load and how the corresponding wire, such as 4BV, under what circumstances, YJV240 what circumstances, the load is much more

According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.

Q:What is the warranty period for wire and cable?

Direct selection of reton's 32-port digital KVM, model is: KS-2032C. Fast transmission, wiring is simple. Want to know the price to ask their website on it.

Q:How are various wire and cable models named?

Cable type a lot, here to give an example: ZRC-YJV22-0.6 / 1KV3 * 25 +2 * 16 This model specification means: C-class flame retardant (ZRC) XLPE insulated (YJ) PVC jacket 22) steel tape armor (0.6 / 1KV) 0.6 / 1 kV (3 * 25) 3 25 square (+ 1 * 16) plus two 16 square copper conductor flame retardant copper core steel tape armored cross-linked poly Ethylene insulated PVC sheathed low voltage electric power.

Q:Rt, the charger did not change, has been no problem before, today just plugged into the charger, the results appear as if the problem, before the out of this problem, and now only ipad power off after the power can not be charged, and ipad start , Then immediately prompted the title, can not charge more

At the same time, security monitoring line itself is a weak line

Q:Cable a fire line power and why the other did not pick up the line with a pen test also have electricity? Answer detailed point

Megohmmeter, such as measuring insulation normal, that is, induction power, the other line after grounding, the pen measured no electricity.

Q:This cable or accessory has not been certified and may not be able to work with this iphone reliably

The installation process is a certain requirement, high and low voltage cable bridge should be installed separately as usual, a wall laying vertical pipeline (slot) or installation equipment, the power distribution between the depth of D1 = 1200 ~ 1500mm; weak Between the deep distance from the D2 = 1100 ~ 1400mm more reasonable. The length L1 and L2 between the power distribution and the weak can be determined according to how much electrical equipment and pipelines (slots) are installed in the room. "Civil building electrical design specifications" proposed "shaft size in addition to meet the wiring spacing and terminal box, distribution box layout must be the size, but also in the box before the left not less than 0.8m operation, maintenance distance" requirements. In the weak equipment, the operation and maintenance distance is not specified in the provisions of the Code for Electrical Design of Civil Buildings, but it should not be less than 0.8m. Cable to wear steel pipe wiring, should be reserved in the floor steel pipe, wiring should be completed after the plug fire fire blocking material. Cable bridge installation should be horizontal, the maximum sag should not be greater than 10 mm; proposed separate installation

Q:IPhone6 This cable or accessories have not been certified how to solve

The color is easy to distinguish. General yellow on behalf of the video line, red white plug left and right audio.
