Q:What is the difference between a KVVR cable and an RVV cable?

The small circle on the wire is marked with a number or letter on the line number. It is set according to the line number on the drawing. A complete wire should be the same for both lines. It is for easy installation and maintenance. And used.

Q:Who provided the more to the sub-gave to whom, thank you for helping

In the low-voltage circuit below 36V, the cross-sectional area of the conductor is not simply considering the safe current-carrying section, taking into account the line drop caused by the length of the transmission line. The cross-sectional area of the wire must also meet the rated voltage supplied to the load side after the voltage drop

Q:Single-wire and stranded general use, instrument control cable can use a single line?

The wire is made of one or several soft wires, with a soft jacket; the cable is made of one or several insulated packets, and the outer layer is covered with a tough outer layer of metal or rubber. Cables and wires are generally made up of three parts: the core wire, the insulating sheath, and the protective sheath. Commonly used cable features are as follows: CEF - EPR insulated neoprene jacket, marine flame retardant power cable. CVV - PVC insulated, PVC sheathed marine flame retardant power cable. OVC cable commonly used BV, BX, RV, RVV series of wires, including: BV - copper core PVC insulated wire, long-term allowable temperature 65 ℃, the minimum temperature -15 ℃, working voltage AC 500V, DC 1000V, fixed laying In the room, the outside can be deposited can also be deposited. BX - copper core rubber insulated wire, the maximum temperature of 65 ℃, apply to the room. RV - PVC insulated single-core cord, the maximum temperature of 65 ℃, the lowest temperature -15 ℃, 250V AC voltage, DC 500V, for the internal wiring equipment and equipment. RVV - Copper core PVC insulated and sheathed flexible wire, allowing long-term working temperature of 105 ℃, working voltage AC 500V, DC 1000V, for wet, mechanical protection requirements, often moving and bending occasions.

Q:Can KVV control cables be used for home heating?

Try to do the cable in the other pipelines above, if it can not do so, then the cable can be in the following. Crossing with different pipelines requires different processing. For example, with the thermal pipeline cross, the thermal line in addition to the original insulation layer, the intersection also need to add insulation tube. No matter what the pipeline intersects the cable, either at the cross or the cable is covered with a protective tube, or other piping plus a protective tube, plus an isolation layer such as a cement tile. For details, please refer to the National Standard Atlas. The intersection in accordance with the national standard to maintain the required distance, the general cable from the other pipeline is greater than 0.5 meters distance.
