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.

How Important are Submarine Fiber Optic Cables? Once Cut Off The US Economy Will Collapse. No Wonder It Was Hidden in The Deep Sea
The Importance of Submarine Optical Cables
Today’s society has been covered by various networks, and the network has closely linked all countries in the world, and the subsea optical cable is the main artery to ensure the interconnection between major regional networks around the world. So how important is the undersea cable, and will the US economy collapse once it is cut off?
Under What Circumstances Do A Double-Hole Copper Lug Work? Are All Two-Hole Terminal Lugs Non-Standard?
What is a terminal lug?
A terminal lug is an old object, as early as 1928, Phoenix Contact invented the world’s first piece of the combined terminal lug, the modern cable terminal lug prototype. And the modern terminal lug is more than this.
What Is Submarine Fiber Optic Cable? How Is It Laid?
The ocean covers more than 70% of the earth’s surface and is rich in resources.
The marine ecosystem is the most important in the world, and human survival and development are closely related to the ocean. Nowadays, we can know the world’s affairs without leaving home, and the submarine fiber optic cable buried deep under the sea plays a vital role.
Things That 95% Of People Don’t Know. The Most Complete Information About Mineral Insulated Cable On The Net
Mineral insulated cable, a copper sheath-wrapped copper conductor core, and magnesium oxide powder as inorganic insulating material to isolate the conductor and the sheath of the cable, the outermost layer can be selected according to the need for appropriate protection sleeve.
1. The Use And Characteristics Of Fire-Resistant Cable
Rigid mineral insulated cable was invented earlier, at the end of the 19th century. The Swiss engineer Arnold Francois Borel on the idea of mineral insulated cable, and received a patent in 1896, 1934-1936, France, and Britain into production after the rapid development.
China also developed in the 1960s, began to be used in the military field, the mid-1980s began industrial production, and was gradually accepted by the construction field in full.
The invention of flexible mineral-insulated fire-resistant cable is relatively late. About the 1970s was born in Switzerland at Stout Cable Company.
Brazing Copper and Aluminum Terminal Lugs Welding Process Standards, Brazing Double-Hole Bimetallic Cable Lugs Welding Principle
Thoroughly remove the oil, dirt, insulation layer, etc. from the base material before welding. heating the base material first when welding, heating the thick part first, then the thin part. heating the copper part first, then the aluminum part.
Move the torch back and forth to evenly heat the welded part, the temperature of the welded part reaches 450-500°C, the welding wire will be added to the welded part.
Let the wire melt evenly into the weld (do not use the flame to heat directly against the wire, the temperature of the base material mainly dissolves the wire).
Then slightly sweep the welding part with the flame to ensure that the welding part brazing material spreads to positioning, remove the gun and let it cool naturally, and you can complete the welding.
Analysis Of Fiber Optic Cable Aging Cases
The aging problem of fiber optic cable is hidden, but it poses a great threat to the operation quality and safety of telecommunication transmission network, which may cause significant losses to enterprises and requires our great attention.
95% Of Transnational Communication Is Achieved By Submarine Cable, You Do Not Wonder How It Is Laid?
On foreign video sites, there is such a video with 1.7 million plays, the video, the naughty shark is destroying the submarine cable, accidentally captured by the camera. Then the question arises, what is the role of the submarine cable? Do sharks do damage from time to time?
Five Minutes to Teach You to Distinguish The Types and Application Scenarios of Submarine Cables
The types of submarine cables can be briefly divided into four aspects.
1. From the structure, is mainly divided into three-core submarine cables and single-core submarine cables. Low- and medium-voltage lines use mostly three-core submarine cable, and high-voltage lines use mostly single-core submarine cable.
