　　Is it better to have a multi-core cable or a single-core cable? The difference between single-core cables and multi-core cables. Power cables are generally divided into single-core, double-core and three-core cables. Among them, single-core cables refer to cables with only one conductor in one insulation layer, while double-core cables refer to cables with two conductors in one insulation layer. In fact, both have their advantages and disadvantages. For example, when the line of a single-core cable is long, when the control circuit with a large current is used or when it is laid in water, in order to prevent or reduce the middle connector, or when single-core cables have better comprehensive safety engineering than multi-core cables, single-core cables can be used.From the demand side, custom multicore cable More in line with the psychological expectations of consumers, willing to pay for the things they like. https://www.linkcablecn.com

　　Is it better to have a multi-core cable or a single-core cable?

　　1. From the current point of view, the current passing through a multi-core cable with the same cross-sectional area is relatively larger than that of a single-core cable, and the load is large.

　　2. From the perspective of power loss, the two ends of the single-core cableare directly grounded, and the metal shielding layer of the cable may also generate circulating current that can reach the current carrying capacity of the cable, which wastes power and forms loss. Multi-core cables are generally three-core cables, because during the operation of the cable, the sum of the currents flowing through the three cores is zero, and there is basically no induced voltage at both ends of the cable metal shielding layer.

　　3. From the perspective of cost, among the wires of the same cross-sectional area, the cost of single-core cables is cheaper than that of multi-core cables, and multi-core cables are slightly more expensive.

　　4. From the perspective of installation, single-core cables appear harder when passing through pipes, while multi-core cables are softer and easier to wire.

　　The difference between single-core cables and multi-core cables

　　2-core cables: When the neutral line of 1kv and below power supplies is directly grounded, the number of cable cores of the single-phase control circuit should be 2-core cables when the maintenance line and the neutral point share the same conductor. For control circuits that can be powered by DC, 2-core cables should be used.

　　3-core cable: When the neutral line of 1kv and below power supply is directly grounded, the number of cable cores of the single-phase power control circuit is: When the protection line and neutral point are separate, it is advisable to use a 3-core cable.

　　4-core cable: 1kv and below 4-core cable (3+1 cable), in which the fourth core is used as a grounding protection, and also carries the unbalanced current and short-circuit capacity of the power supply system. (To learn more about cable technology, please click here, a lot of dry goods are waiting for you) Its size is determined by the unbalanced current and short-circuit capacity, but generally cannot be less than 1/2 of the phase line.

　　5-core cable: 1kv and below three-phase four-wire distribution room system, some electrical equipment distribution lines with higher safety requirements, and some communication centers and automation equipment that must ensure power safety and anti-interference grounding, it is advisable to use 5 copper core cable TN-C distribution room system, so that the protection line (PE line) and neutral point (PN line) are independent, and the cable core section is generally 3 large and 2 small or 4 large and 1 small or 5 large.

　　Multicore Flexible Cable supplier.jpg

　　The difference between 4-core cable and 3+1 core cable: 1kv and below three-phase four-wire distribution room system, when the protection line and neutral point share the same conductor, 4-core cable should be used, and the method of 3-core cable plus single-core cable to form a circuit cannot be used, or even the method of directly using the metal sheath or armored cable layer of 3-core cable as the neutral point. Otherwise, when the 3-phase current is unbalanced, it is equivalent to the operation of a single-core cable, which is easy to cause DC interference.

　　membrane switch types

　　Types of membrane switches

　　1. Flexible membrane switch

　　Flexible membrane switch is a typical form of membrane switch. This type of membrane switch is called flexible because the mask layer, isolation layer, and circuit layer of the membrane switch are all composed of flexible films of various properties. The circuit layer of the flexible membrane switch uses polyester film (PET) with good electrical properties as the carrier of the switch circuit pattern. This layer is also divided into hand-feel springs and upper and lower circuits. Due to the properties of polyester film, the membrane switch has good insulation, heat resistance, folding resistance and high resilience. The graphics of the switch circuit, including the switch connection and its lead wires, are printed with low-resistance, low-temperature cured conductive paint. Therefore, the composition of the entire membrane switch has a certain degree of softness, which is not only suitable for use on flat bodies, but also can be used with curved bodies. The lead wires of the flexible membrane switch are integrated with the switch body. When making the connection of the group switch, they are gathered at a certain place on the membrane and extended outward according to the position specified in the design and the standard line spacing. They are connected to the rear circuit of the whole machine as soft, arbitrarily bendable and sealed lead wires.

　　membrane switch types

　　2. Rigid membrane switch

　　Rigid membrane switch refers to a switch whose graphics and circuits are made on a common printed circuit copper-clad board. The characteristics of rigid membrane switch are convenient material acquisition, stable process, low resistance, and certain components in the circuit can be directly welded on its back. In the case of a small area, the rigid lining layer can be omitted. Rigid membrane switches generally use metal guides as the contact points for conducting the labyrinth, so they have a better feel. The disadvantage is that they are not as convenient to install in the whole machine as soft membrane switches, and often require welding and lead-out through flat cables. In addition to buzzer signals and LED indications, the information feedback of rigid membrane switches generally uses metal feel springs.

　　membrane switch types

　　3. Flat membrane switch

　　The buttons on the membrane switch use different colors to indicate the position, shape and size of the key body, which is more common in the initial stage of membrane switches. Three-dimensional membrane switch: Usually, the buttons on the membrane switch only use colors to express the position, shape and size of the key body. In this way, the accuracy of the operation can only be identified by the operator’s vision. Since there is no appropriate feedback information to indicate whether the finger is pressed within the effective range of the switch to make the switch operate, it affects the confidence in monitoring the entire machine and the speed of operation. A membrane switch that makes the switch key body slightly raised and slightly higher than the panel to form a three-dimensional shape is called a three-dimensional key switch. The three-dimensional key can not only accurately give the range of the key body, improve the recognition speed, and make the operator’s sense of touch more sensitive, but also enhance the decorative effect of the product appearance. The production of three-dimensional keys.
