1. Looking at the appearance, qualified cable and wire packaging is better, with a certificate of conformity, and the wire has printed company information, product information, product model, product specifications, 3C certification and other information.2. Weighing, wire and cable as a special pro... READ MORE
1. The site conditions are relatively poor. The environment and process requirements for cables and connectors are very high when they are manufactured in the factory, and the temperature, humidity and dust on the construction site are not easy to control.2. Failure to strictly follow the process c... READ MORE
The electrical properties of cable and wire can be significantly affected by insulation. As a result, high-frequency communication cables will require polyethylene (PE) insulation because attenuation and capacitance are minimal when using this type of insulation. In addition, insulating materials a... READ MORE
Insulation type of power cable and wire:Insulation typeAn insulator is a material (a non-conductive material) that can resist the flow of electric current. It helps resist current leakage and prevents it from contacting other conductors. This helps to maintain the integrity of the wires against env... READ MORE
The outer sheath structure of cable and wire is mainly to protect the cable core from external influence and mechanical damage. The following types are commonly used:1. Fiber woven layer: This kind of protective layer structure is simple, soft and thin. As long as the maintenance effect is simple, ... READ MORE
There are many types of wires, which can be divided into many types according to different applications. Compared with wires for other purposes such as engineering, household wires have relatively lower requirements for the functions of wires. Specifically, household wires are classified as follows...

Fire-retardant measures for cable and wire include:(1) Apply fireproof paint on the cable surface.(2) Wrap the parts of the cable that need to be flameproof with fireproof tape.(3) The holes where the cable passes through the wall, the bottom of the plate, and the shaft are tightly sealed with refr...

How to prevent the fire of cable and wire:1. Enhance cable operation monitoring to avoid cable overload operation.2. Carry out cable test regularly, and deal with it immediately if any problem is found.3. Install the fire alarm device to detect the fire immediately to avoid the cable fire.4. The ca... READ MORE
In addition to the measurement of basic parameters such as voltage, current, resistance, capacitance, and transistor, the digital multimeter can also be used to further expand its function and achieve the purpose of multi-use. A method of judging wire and cable breakpoints with a digital multimeter... READ MORE
There is no strict boundary between "wire" and "cable". Products with a small number of cores, small product diameters, and simple structures are generally called wires, those without insulation are called bare wires, and others are called cables; those with larger conductor cross-sections (Greater...
