Recent cable industry information shared by the world’s top cable manufacturers. The most authoritative cable and wire website.
Among the many classifications of cables, control cables are also one of the most frequently seen major classifications.
Control cables are used everywhere in life. So for individuals, how to use and choose control cables in general? Today ZMS cable engineer takes you to understand the use and selection of control cables.
No longer do we see a hodgepodge of cables everywhere in life. They have been cleverly placed in the air and called overhead cables. What is this all about? Today ZMS cable editor takes you to understand overhead cables.
Many people have heard of nickel metal and may not have seen it, but it is found everywhere in life. For example, the copper nickel-plated cables that we all come into contact with daily. Recently, there was this report about nickel.
Brazilian mining company Vale said Wednesday that global demand for nickel will grow 44 percent by 2030 over this year’s forecast due to strong demand for electric vehicle batteries.
The flammability of power cables, and string extension, once the fire, the danger is serious, especially in power plants and large substations, once the fire occurred, the ripple of other circuits. Therefore, the fire prevention technology of power cables is one of the important technologies for the normal operation of electrical systems.
The shielding layer of the cable has different roles in the materials and structures used.
Shielding layer according to the role of wire shielding, insulation shielding, and metal shielding.
For the cable withstand voltage test, I believe many people are curious about what it is for, and also curious about what uses. The following ZMS cable company’s editor will take you to understand.
Cable series resonance test device uses the way to adjust the frequency of the power supply so that the reactor and the capacitor are under test to achieve resonance. The test product to obtain high voltage high current is a new method and trend of the current high voltage test, which has been widely used at home and abroad.
The cable series resonance test device adopts a special SPWM digital waveform generation chip with 16-bit frequency resolution. The frequency fineness can reach 0.1Hz at 20~300Hz. The orthogonal non-synchronous fixed carrier modulation method is adopted to ensure good output waveform in the whole frequency interval; the power part adopts the IPM module to ensure the stability and safety of the instrument under the minimum weight.
Regarding the allowable long-term working temperature of wire and cable cores, rubber insulation is usually 65℃, PVC insulation is 70℃ and cross-linked polyethylene insulation is 90℃. The maximum allowable temperature of the conductor during a short circuit (the longest duration does not exceed 5s): is 160°C for PVC insulation and 250°C for cross-linked polyethylene insulation. ZMS cable production company to introduce the difference between XLPE cable and PVC cable.
Cables are everywhere in our lives, and even the types and models of wires can dazzle everyone. Today, the ZMS cable manufacturer’s editor explains the difference between coaxial cable and ordinary cable.
Generally speaking, power cables are not allowed to enter the water during production, and the cable must be dry inside because of the severe electric field voltage test, and thus the cable that enters the water cannot leave the factory.
An electric vehicle charging cable is a flexible cable used to connect electric cars to charging posts or power outlets. The high-quality oxygen-free copper conductor ensures superior conductivity, the TPE insulation material is soft and high strength, and the sheath is made of high-performance TPE. it has the characteristics of weather resistance, high/low-temperature resistance, friction resistance, etc.
