Routine test for electrical performance of plug power cord

Why did you talk about this topic? In fact, it's simple and depressing. I thought this was originally a very simple problem, but I visited so many factories and found that quite a few engineering and quality control technicians were also unable to clearly understand the purpose, principle, and parameters of electrical testing; Causes and consequences of adverse events; How to use the instrument correctly, etc. Therefore, taking the opportunity of this exchange meeting, I would like to share my own experiences over the years with you. I also hope that colleagues and advanced critics can make corrections.

Test method for insulating strength of insulated wires and cables

The insulation strength of wires and cables refers to the ability of insulating structures and materials to withstand the action of electric fields without breakdown damage. In order to check the quality of wires and cables and ensure their safe operation, insulation strength tests are generally required for all types of wires and cables. The insulation strength test can be divided into withstand voltage test and breakdown test.

Analysis of the characteristics of PVC wire winding film

PVC wire winding film is widely used in a wide range of fields, with its small size and high viscosity, which is convenient for wire winding and provides integrated packaging for scattered goods, instead of small storage boxes. Because it can reduce the transportation and packaging costs of bulk goods by more than 30%, it is widely used in the integrated packaging of various products such as hardware, minerals, chemicals, pharmaceuticals, food, machinery, and so on; In the field of warehouse storage, stretch-wound film pallet packaging is also widely used in foreign countries for three-dimensional storage and transportation to save space and land.

Analysis of the real difference between national standard cable and non-standard cable

Over the years, cable practitioners have been familiar with a sensitive topic: It is too difficult to sell national standards. They all say that their cables are national standards, while non-standard ones also say that their own are national standards. As a result, they have an advantage in quotation, which once made cable market practitioners feel helpless;

How to achieve breakthrough innovation in management for wire and cable enterprises

When purchasing a household stainless steel shower, what should we pay attention to& nbsp; Showers are also known as shower heads or shower heads. It is said that it is used to water flowers. Later, people discovered that it was also suitable for bathing, and gradually developed into the current shower. The bathroom in every family is basically equipped with a shower. Showers have developed rapidly and come in a variety of styles. First, let's take a look at what material the shower is made of. ABS engineering plastic sprinklers account for over 80% of the market share. The stainless steel sprinklers we see in stores are all made of this material. The advantages of ABS plastic nozzle are that it has multiple styles and shapes, and can be equipped with multiple water outlet functions, which is very practical; There are few styles of copper nozzles. Generally speaking, there are only a few models. Using copper as a model is not as convenient as using plastic, and the cost is high. Therefore, the development of copper nozzles is limited. The common copper nozzle has only one water outlet function; Stainless steel sprinklers are rare. Like a copper nozzle, it is not easy to shape. Most stainless steel showers have only one way to get the water out. The advantage of stainless steel sprinklers is that they can be made into large sizes. Some of them may be one meter long and wide. We saw large overhead stainless steel sprinklers in the hotel, which are basically made of stainless steel. We're familiar with handheld devices
