浅谈交联聚乙烯绝缘电力电缆

  XLPE insulated power cableIt is a common cable category in civil engineering, including ordinary type, flame retardant type, fire-resistant type and halogen-free low-smoke flame retardant type.XLPE insulated power cableEnvironmental stress resistance, high mechanical strength, chemical resistance, excellent electrical performance, simple structure, light weight and convenient use.

  1.XLPE insulated power cablePurpose: This product is suitable for power lines with rated voltage (U0 / U) from 3.6 / 6 to 26 / 35KV to transmit and distribute energy.

  2.XLPE insulated power cableStandard: aluminum core plastic insulated power cable, GB12706-91 rated voltage 35KV and below copper core.

  3.XLPE insulated power cableUse characteristics:(1) When laying cables at an ambient temperature of not less than 0°C, there is no need to preheat. There are no restrictions on cable laying. (2) The long-term allowable working temperature of the cable core wire shall not exceed the following regulations: 90 ℃ for cables with PVC sheath; 80 ℃ for cables with polyethylene sheath. (3) When the wire core is short-circuited (for a maximum of 5S), the temperature should not exceed 250°C. (4) The minimum bending radius when laying the cable is as follows: single-core cable: 20(d D)± 5%; three-core cable: 15(d D)± 5%, in the formula: d is the actual outer diameter of the conductor, D is the actual outer diameter of the cable.

Dry goods sharing, a minute to take you to understand the purchase of wire and cable points

What are the main points of purchasing wires and cables? Let's take a look. As the main carrier of power transmission, wire and cable are widely used in electrical equipment, lighting circuits, household appliances, etc. Its quality directly affects the quality of the project and the safety of consumers' lives and property. There are many wire varieties on the market, and appropriate wires should be used according to their own power load.

What are the precautions for wires and cables? Let's take a look. Common cable faults: wire surface markings-according to national standards, the wire surface should have continuous markings of the manufacturer's name, product model and rated voltage. This helps to find the manufacturing plant in time when there is a problem during the use of the wire, and consumers should pay attention to this when buying the wire.

What are the product classifications of wires and cables for electrical equipment?

What are the product classifications of wires and cables for electrical equipment?

There are many kinds of wire and cable products for electrical equipment on the market, which are difficult for ordinary consumers to distinguish. So what are the main categories of wire and cable products? What are the product naming principles of wire and cable? The editor brings you a brief understanding of relevant content knowledge.

What is the use of wires and cables for electrical equipment?

What is the use of wires and cables for electrical equipment?

The wires and cables for electrical equipment are mainly used for internal or external connection of electrical equipment, low-voltage transmission lines and various electrical signal transmission lines. Generally speaking, except for power cables, communication cables and magnet wires, most insulated wires and cables are classified as wires and cables for electrical equipment.

What are the classification of wires and cables for electrical equipment?

What are the classification of wires and cables for electrical equipment?

Electrical equipment with wire and cable is a large class of wire and cable products, a wide range of applications, many varieties, many series, large output, process type complex. The rated voltage of wires and cables for electrical equipment is low, and the working voltage is 450/750v and below, which is not more than 0.6/1kv. The working voltage of signal and instrument cables is usually 300/500v and below. The ampacity of the cable is determined according to the requirements of the cable.
