Storage and transportation of wire and cable products are two very important aspects. If the storage and transportation methods are not appropriate, the quality of wire and cable products can cause damage and affect the safety of use. So, in the storage and transportation of cable products, what matters need our attention?
INFORMATION
Welcome to the ZMS CABLE information blog, here is the cable industry knowledge sharing and technology popularization of the professional world. In this section, we focus on cable technology, product applications, and industry knowledge, carefully crafting a series of easy-to-understand and practical content, to provide readers with authoritative technical support and comprehensive industry interpretation.
Carbon Fiber Cable Construction Typical Defects And Operational Considerations
The full name of the carbon fiber wire is carbon fiber composite core aluminum stranded wire (ACCC), the wire from the beginning of this century has only been used for a relatively short period of more than ten years, there is a certain amount of experience in the application. Carbon fiber wire has high strength, lightweight, high modulus of elasticity, small coefficient of linear expansion, small arc sag, small line loss, large capacity (allowing high temperature), corrosion resistance, long service life, and other characteristics. Especially suitable for coastal, mining areas corrosion intensity, high fouling strength, the wire is easy to dance the use of the environment.
7 Common Faults In 10KV Overhead Cable Transmission Lines, As Well As The Causes Of Faults And Preventive Measures
10KV overhead cable transmission line common faults are 7 kinds
1 Single-phase grounding fault
Single-phase grounding is the most common fault in the power distribution system, mostly occurring in wet and rainy weather. Single-phase grounding not only affects the normal power supply of users, but also Hunan Sunshine Electronics School maintenance experts believe that: it may produce overvoltage, burn equipment, and even cause an inter-phase short circuit and expand the accident.
Design, Production, and Installation of Cable Termination and Joints for 10kv Cable Projects
1 Scope of application
It is suitable for the installation of 10kV XLPE cable cold shrink termination and joints in distribution network projects.
A Brief Summary Of “Three Spans” Of Transmission And Distribution Lines
With the continuous upgrading and construction of power grids and transportation infrastructure, transmission lines “three across” related issues are becoming more frequent. Such as improper handling, which will likely lead to significant public safety and grid security incidents. So for the transmission lines “three across” section, construction standards and other aspects must be strictly controlled. This paper provides a summary of this issue.
The Production Process and Selection of Cross-Linked Insulated Cables
Although there are many varieties of cross-linked insulation, they are mainly divided into two categories: physical and chemical cross-linking. The quality of the insulation is identical, so in the national standard GBl2706-91, there is no distinction between the cross-linking methods used.
Cross-linked insulation has been dominant in power cables, replacing oil-paper insulation, and gradually replacing PVC plastic insulation. Although there are many varieties of cross-linked insulation, it is mainly divided into two categories: physical and chemical cross-linking, and its insulation quality is completely consistent. Therefore, in the national standard GBl2706-91, no distinction is made as to which cross-linking method is used.
Is It Necessary To Use An Aluminum Alloy Cable With Special Cable Terminal Blocks For An Aluminum Alloy?
With the development of the cable industry, the advantages of copper-core cable are more. Copper-core cables occupy an absolute advantage over aluminum-core cables in the cable market. However, the high price of copper-core cable also caused an increase in production costs, and also bad construction. The aluminum-core cable as a cable industry “foreign army” emerged, in the market’s favor.
Standards For Cable and Terminal Lug Crimping Specifications
I. Remove Metal Stains, Get A Clean Cable Terminal Lug
Removing metal stains prior to cable connection is an important prerequisite for ensuring cable lug quality.
- Remove metal residues from the conductor surface by wiping.
- Inspect the conductor connection section and remove any visible oxides.
- Ensure that the conductor surface is free of metal residues, otherwise, conductor corrosion in the contact area will occur.
- Ensure that the decontamination of all components has been completed.
What is The Purpose of Low-Voltage Shielded Cables? And The Way to Prevent Damage to Shielded Cables?
What is The Purpose of Low-voltage Shielded Cables?
A shielded cable is a transmission line that uses a metal mesh braid to encase the signal line. The braiding layer is usually red copper or tinned copper. The wire and cable industry is the second-largest industry in China, after the automobile industry. The product variety satisfaction rate and domestic market share are over 90%. In the world, China’s total wire and cable output value has surpassed that of the United States, becoming the world’s largest wire and cable producer. Along with the rapid development of China’s wire and cable industry, the number of new enterprises has been rising, and the overall technical level of the industry has been significantly improved.
Is Low Smoke Halogen-Free and Environmentally Friendly Cable The Same? What Is The Difference?
Environmentally friendly cables are those that do not produce toxic and harmful substances before, during, and after use. For example, it does not contain heavy metals such as lead, cadmium, hexavalent chromium, and mercury, and does not contain brominated flame retardants. The environmental performance test by SGS recognized testing agency, in line with the EU environmental protection directive and higher than its index requirements. No harmful halogen gas, no corrosive gas, less fever when burning, no soil pollution of wire and cable.
