Identify BVR, BV and RV wires and cables？
2020-04-30 [ Industry News ]
1. The difference between BVR, BV and RV wire and cable.1. The difference between B and R, the former is a cable (wire) for fixed wiring, and the latter is a flexible wire for connection.2. The difference between BV, BVR and RV is the conductor structure. In general, BV uses the first conductor, BVR uses the second conductor, and RV uses the fifth conductor.3. BV is generally a single core wire with a hard conductor; while BVR is a soft conductor; the two resistance values are the same. The RV is softer than them, and the insulation requirements are different.Guangzhou Gaaye Electronics Co., L......
Comparison of copper core cable and aluminum core cable
2020-04-29 [ Industry News ]
Copper core cable has advantages over aluminum core cable:1. Low resistivity: The resistivity of aluminum core cable is about 1.68 times higher than that of copper core cable.2. Good ductility: the ductility of copper alloy is 20 ~ 40%, the ductility of electrical copper is above 30%, while that of aluminum alloy is only 18%.3. High strength: the allowable stress at room temperature, copper is 7 ~ 28% higher than aluminum respectively. Especially the stress at high temperature, the difference between the two is even further.4. Anti-fatigue: aluminum is easy to break after repeated bending, but......
Do you know the difference between cable and fiber optic cable?
2020-04-28 [ Industry News ]
1. The difference in material: the cable uses metal material (mostly copper and aluminum) as the conductor; the optical cable uses glass fiber as the conductor.2. The difference between transmitted signals: electric signals are transmitted by cables; optical signals are transmitted by optical cables.3. Difference in application range: cables are mostly used for energy transmission and low-end data information transmission (such as telephone); optical cables are mostly used for data transmission.Therefore, the working principle, structure, material, transmission signal and application range of ......
There are more and more electric vehicles. Are you choosing the right charging cable?
2020-04-27 [ Industry News ]
Gaaye charging pile cables are mainly used for electric vehicle charging equipment and charging ports, or vehicle charging and discharging early warning control systems with control signal transmission functions for charging saturation and safety warning. Working environment temperature -25 ℃ ~ 50 ℃, maximum line temperature 70 ℃. The rated voltage is AC450 / 750V, DC1000V. The short-circuit allowable temperature can reach 200 ℃ for 5 seconds. Insulation and sheath use halogen-free thermoplastic elastomer materials with excellent flexibility and meet EU ROSH requirements. Cold resistance, wear......
How can I prevent damage to the wires?
2020-04-26 [ Industry News ]
1. Determine the safe current carrying capacity of the wireWhen using electrical appliances at ordinary times, pay attention to the safe current carrying capacity of the wires in the circuit. If the current of the electrical appliances used exceeds the safe current carrying capacity of the wires, this will easily affect the service life of the liquidation, although no changes have been seen in a short time However, the problem of tripping and short circuit is easy to occur after a long time, and it is also easy to cause the accelerated aging of the wire, which will naturally cause a very serio......
