  • Overhead insulated conductor types

    Types of overhead insulated conductors The 1kv national standard for overhead insulated conductors is about cables. It belongs to the mutual erection of elongation by pole towers. Relatively clear, the transmission and distribution network makes the line to the ground absolutely free of air. The previous distribution of power (below 10kV except 380V) usually also uses bare decline, but it has been in the wild for 30 years of reform and opening up.

  • What are the special requirements for overhead insulated wires

    What are the special requirements for overhead insulated conductors? Let's give you a brief introduction. RVV: Multi-stranded flexible wire, that is, the core wire is composed of multiple-stranded copper wires. RVV wire is a commonly used cable for weak current systems. The number of core wires is variable, there are single or multiple, and there is a sheath on the outside. But there is no special requirement for the arrangement of the core wires

  • What are the advantages and disadvantages of overhead insulated conductors?

    What are the advantages and disadvantages of overhead insulated conductors? Because insulated conductors have an extra layer of insulation, they have superior insulation properties than bare conductors, which can reduce the distance between lines, reduce the insulation requirements for line support, and improve the circuit of lines installed on the same pole. number. The overhead insulated wire has an insulating layer on the outer layer, which is less oxidatively corroded than the bare wire and has a strong anti-corrosion ability, which can extend the wire.

  • Characteristics of overhead insulated conductors

    Characteristics of overhead insulated conductors I. Principles of overhead insulated conductor cables: The series of overhead insulated conductor cables are composed of compacted copper, aluminum (aluminum alloy) conductors, inner shields and weather-resistant insulation materials and outer shields. Power transmission characteristics and strong mechanical properties of overhead cables. Compared with bare wires, this product has a small laying distance, safety and reliability.

    Overhead insulated wire installation 1kv70 how many 6 insulated insulated wire conductors are with the metal, which belongs to the decline of the tower by the pole tower refers to the best effort in the business community height thickness width degree highly needed conversion of electrical energy. Most of the ground insulation of overhead lines and clear transmission and distribution network rely on workshops. Most of the previous power distribution conversions (below 10kV except 380V) also chose bare decay for a long time, but

  • What is the difference between flame retardant cable and fire resistant cable

    The concept of flame-retardant cable and fire-resistant cable are different, and correct understanding can help correct design and selection. It is easy for ordinary people to confuse the concept of flame retardant cables and fire resistant cables. Although flame retardant cables have many advantages that are more suitable for chemical companies, such as low halogen, low smoke and flame retardant, etc., in general, fire resistant cables can replace flame retardant cables. ,

  • How to distinguish the cracking mechanism of steel core aluminum stranded wire with aluminum stranded wire and high-density polyethylene sheath for overhead insulated cables:

    How to distinguish the cracking mechanism of steel core aluminum stranded wire and aluminum stranded wire and high-density polyethylene sheath for overhead insulated cables: Steel cored aluminum stranded wire and aluminum stranded wire are both wires without external insulation, which is what we commonly call " "Bare wires", people who do not understand the cable industry may not know how to distinguish between steel core aluminum stranded wire and aluminum stranded wire. They are all aluminum wires in appearance. So how to distinguish steel core aluminum stranded wire

  • What is aluminum alloy wire and cable and how to choose aluminum alloy cable?

    What is aluminum alloy wire and cable and how to choose aluminum alloy cable? Unlike traditional copper-core cables, aluminum alloy cables (referred to as alloy cables) are made of high-elongation aluminum alloy materials. Pure aluminum is made by adding iron and other materials, and undergoes a tight-stranding process and special Annealing to "squeeze" the voids in the aluminum alloy

  • What are the structural characteristics of mining rubber cable?

    Today's Xinchaoda cable mainly introduces the structural characteristics of mining rubber cable. One: conductive wire core. 1. Use softer, fine-diameter copper single wire, bundle at small pitches, and twist. The bending and torsion of the entire cable is also affected by the insulation and sheath structure, so it cannot be considered that the thinner the monofilament, the smaller the pitch is, the better. 2. Using the same direction stranding and retwisting can improve the flexibility.
