The evolution has progressed from simple telephone and telegraph cables to thousands of pairs of cables, including coaxial cables, optical fibers, and data cables, even to combined communication cables. These products typically feature small and uniform structural dimensions, with high manufacturing precision requirements.

Electromagnetic Wire (Winding Wire)

Primarily used for various motors, instruments, and meters.

Flexible Fire Resistant Cable

1. Excellent fire resistance properties; the fire resistance rating meets not only the international GB12666.6A class's 950℃ for 90min requirement but also the UK BS6387-1994 specified A grade 650℃ for 3h, B grade 750℃ for 3h, and C grade 950℃ for 3h. Additionally, it can withstand water spray and mechanical impact during combustion.

3. Large cross-section single-core cables can reach up to 1000mm², while multi-core cables can reach up to 240mm².

4. Flexible, the cable can be coiled on a drum, with a bending radius ≥ 20D, where D is the outer diameter of the cable.

During overload conditions, the working temperature of the fire-resistant cable is allowed to reach up to 250°C.

7. Corrosion-resistant, organic insulated fire-resistant cables may require plastic or iron piping, which can easily age and become brittle, and iron piping is prone to rust; fire-resistant cables with copper sheath do not need to be enclosed in pipes, as the copper sheath offers excellent corrosion resistance.

Section 7: Common Issues with Recycled Cable Recovery Products

Common faults in cable lines include mechanical damage, insulation damage, insulation dampness, insulation aging and degradation, overvoltage, and overheating faults in cables. When the above faults occur, the power supply to the faulty cable should be disconnected, locate the fault point, inspect and analyze the fault, then proceed with repairs and testing. Remove what is necessary, and only restore power after the fault is eliminated.

The most direct cause of cable failure is the reduction of insulation, leading to breakdown.

Mainly includes:

a. Overloading operation. Prolonged overloading operation will cause the cable temperature to rise, lead to insulation aging, and eventually result in insulation breakdown, reducing the construction quality.

b. In electrical aspects: cable head construction does not meet requirements, poor cable head sealing allows moisture intrusion, reducing cable insulation performance; no protective measures were taken during cable laying, resulting in damage to the protective layer and decreased insulation.

c. Civil engineering issues include: Inadequate drainage in manholes and trenches, cables being submerged in water for extended periods, damaging their insulation strength; manholes being too small, resulting in insufficient cable bend radius and long-term external force damage from compression. The main cause is often rough and uncontrolled construction by machinery during municipal projects, which can dig through or cut cables.

d. Corrosion: Long-term chemical or cable corrosion can lead to the failure of the protective layer and a decrease in insulation.

e. Poor quality of the cable itself or cable head accessories, poor cable head sealing, dissolved insulation glue, cracking, leading to resonance phenomena at the station being treated as a line break fault, where the inter-phase capacitance and ground capacitance of the line form a resonance circuit with the excitation inductance of the distribution transformer, thereby exciting ferromagnetic resonance.

Harmonics Caused by Open Circuit Faults

In severe cases, the resonance of broken wires can cause the superposition of high-frequency and fundamental frequency resonances, which may lead to overvoltage amplitudes reaching 2.5 times the phase voltage [P], potentially causing neutral point displacement in the system, overvoltage in windings and conductors, and in extreme cases, insulation breakdown, lightning arrester explosion, and damage to electrical equipment. In some instances, the phase sequence of the load transformer may be reversed, and overvoltage may be transmitted to the low-voltage side of the transformer, causing harm.

Key measures to prevent overvoltage due to open-circuit resonance include:

(1) No circuit breakers are used to prevent partial phase operation.

(2) Enhance line inspections and maintenance to prevent wire breaks.

(3) Do not leave an unloaded transformer connected to the line for an extended period.

(4) Utilize ring main or dual power supply.

(5) Add inter-phase capacitors on the transformer side.

The principle is: using capacitors as energy-absorbing elements to absorb energy during transient processes, thereby reducing the intensity of impact disturbances to suppress resonance. By adding an inter-phase capacitor ΔC, on the transformer side, the value of 8[Co + 3(C U + A0)/Ca] increases, thereby increasing the required capacitance for the equivalent capacitance C and the equivalent electromotive force Eo. The required capacitance can be calculated using the method described in reference [6]. (6) Using transformers with good excitation characteristics helps to reduce the likelihood of overvoltage due to broken wires.

Power cables are used for the transmission and distribution of electrical power. They are commonly employed in urban underground power grids, power station outgoing lines, internal power supply for industrial and mining enterprises, and underwater transmission lines for rivers and seas.

In electrical power lines, the proportion of cables is gradually increasing. Power cables are cable products used in the main transmission lines of the power system for transmitting and distributing high-power electrical energy.

In the midst of a cable market filled with mixed quality, with an endless stream of substandard wire and cable products, how do you choose qualified cables?

A 20-year veteran from a cable factory shares: Here are the key points for power cables!

1. Copper core is key

High-purity oxygen-free copper, anti-aging. High conductivity, low loss, super strong current load capacity

2. Low resistance required

Low resistance, higher conductivity; resistance directly affects the energy consumption during transmission, the lower the resistance, the more energy-saving.

3. Insulation should be even and uniform in thickness

Prevent breakdown, ensure safety—Huaxiang uses high-quality equipment to guarantee the cable's low eccentricity, even thickness, effectively preventing wire and cable breakdown, and ensuring safe electrical use.

Wires and cables are widely used in industrial production and in the daily lives of the people. Inspections of wire and cable products in recent years have shown that there is a significant problem of cutting corners and using substandard materials. The prominent issues include the copper core material not meeting purity standards, insufficient cross-sectional area dimensions, leading to excessive conductor resistance, increased line losses, enhanced energy consumption, and localized overheating of the cables, which increases the risk of safety accidents. Wire and cable products involve personal and property safety, and the country implements an industrial product production licensing system and the CCC mandatory certification system for these products.

(Weighting Method)

For power cables with a cross-sectional area of 30mm2 or more, cut a 1000px section (preferably from the middle, as some cable manufacturers make both ends meet the standard requirements to pass inspections), remove the jacket, shielding, and insulation materials, and pull out any single wire. Measure its length with a ruler and weigh it using an electronic scale with a precision of 0.01g. Calculate the wire's cross-sectional area based on the density of the material (copper is 8.92g/cm3, aluminum is 2.70g/cm3). If the calculated area has a negative deviation from the marked area exceeding 10%, it can be preliminarily determined as an unqualified product and must be sampled for inspection; if the negative deviation is between 5-10%, samples can be selectively taken for inspection. In actual cases, most of these products are found to be unqualified after inspection; if the negative deviation is below 5%, sampling should be done with caution, as most of these products are found to be qualified after inspection in actual cases. Always measure each wire on-site to ensure the data accuracy. We also have
