Wire is a special product that is related to the personal safety of every household and whether all areas can operate normally. It has a wide range of applications, especially in temporary wire winding and home decoration. The wires and cables of counterfeit and shoddy products may cause short-circuit faults and electric shock accidents if they are light, and fire accidents and casualties if they are serious. This is why we refuse to use fake and inferior cables. Let me tell you how to identify fake and shoddy wires.
The specific method commonly used by manufacturers is to work hard on the length of wires and cables. The more common one is the cloth wires packaged in whole rolls. According to industry standards, each roll is required to be 100 meters, and the measurement verification deviation should not exceed 0.5%. The total length of the coiled wire is 100 ± 0.5 meters, while many wire manufacturers unscrupulously mark 100 ± 20 meters on the qualified card, and the specific length is only 80 meters long.
The temperature of a wire with too high resistance is likely to be too high under the same AC current, which will accelerate the embrittlement of the outer insulation layer, causing short-circuit faults and fire accidents; and because the resistor exceeds the standard, it will continue to greatly increase the transmission and distribution The energy consumption of the whole process of electricity increases the cost of electricity consumption.
One is the idea of making copper wires. Copper conductors account for 80% of the cost of wires. Unsatisfactory manufacturers first reduce the quality of copper materials. Using much cheaper residual copper, recycled copper, or even copper smelting by local methods, the copper content is extremely unstable, resulting in a sharp increase in the resistance of copper electrical conductors. The second is to reduce the amount of copper used and reduce the specific cross-section of the copper core. The direct consequences of these two methods are that the wires are overheated during use, destroying the insulating plastic, causing short circuits and causing fire accidents.
The second is to play tricks on the plastics commonly used in the insulating layer, which degrades like copper materials. The price difference between a ton of recycled insulating layer materials and qualified PVC plastic powder is nearly 2,000 yuan, but the recycled insulating layer materials have high residue content and low impact toughness. , the anti-aging properties and electrical insulation performance can be reduced, which will directly cause the wires to be prone to short circuits.
XSD cable manufacturer: teach you to identify inferior cables
First of all, look at the packaging of the device. The plastic skin of the reliable wire is soft and smooth, and the color is well-proportioned. On its surface, the established production date should also be printed, as whether there is a symbol of the my country Welder Product Quality Certification Association and a production license number on the package, to see if there is a quality system certification mark; to see if the certificate is standard; Check to see if there is a company name, place of manufacture, test stamp, date of manufacture; check if there is a trademark logo, specification model, working voltage, etc. printed on the wire... At the same time, the handwriting must be clear and not easy to erase.
Look at whether the plastic skin on the surface of the wire is bright in color and fine in material. It can be bent many times with a single wire head, but it is also good for soft touch, good impact resistance, plastic or vulcanized rubber, and no cracks on the wire conductor and insulator. Authentic. Doing one thing and doing one thing well are two different things. It is the same for everyone. For a cable manufacturer, simply selling products and selling products and services are two different things. At least for customers, the inner feeling is The difference is that customers come to purchase cables. If we can take the customer’s affairs into consideration and consider everything from the perspective of the customer, how can the customer not feel the sincerity from XSD Cable?

Wire and cable manufacturer: XSD cable, 10 years of experience in the production of engineering wire and cable, according to project needs Carry out cable customization, cable product selection, engineering guidance and installation; choose a major, choose and build XSD Cable, and provide you with a one-stop solution for engineering cables and wires procurement.
Weak current installation cables can choose PVC insulated PVC sheathed data signal cable PVV type. If there are many shielding standards, choose high-voltage polyethylene insulating strip steel-wrapped shielding plastic cable KVVP" type, aluminum-clad cable KX) type or multi-core shielded cable and computer cable DJ-VVP type.
Low-voltage power engineering cables generally use high-voltage polyethylene insulated high-voltage polyethylene sheathed power engineering cables VV or VLV type. Armored cables and jackets are layer picked.
Directly buried cables use high-pressure polyethylene or PVC sheathed inner armored cables, and mine operation cables are denoted as 223.
For laying cables that may bear tension or may cause soil movement, thin stainless steel wires and thick stainless steel wire armored cables shall be used, denoted as 32.
XSD cable manufacturers: how to choose mine cables
1. When the working temperature is lower than -15°C, mine cables are not suitable for laying ordinary PVC insulated and sheathed cables.
2. The cable laid on the bridge frame or installed and laid in the threading pipe shall be an all-plastic cable without armored cable, no record.
3. The cables laid on the E-shaped support frame are generally armored cables, and mine rubber-sheathed cables are recorded as 20.
4. Use PVC outer sheath cables for laying in wet and cold or corrosive places, denoted as 22.
5. For laying in fire-risk sites, chemically cross-linked polyvinyl chloride insulated polyvinyl chloride sheathed flame-retardant cables are used, and mine cables are recorded as 22.
Since our establishment in 2013, XSD Cable has been one of the professional manufacturer in the field of wire and cable.
