Flexible fireproof cable
Yanggu Haohui FlexibleFireproof cableThe characteristics of the, small make up to introduce to you.
1. The fire resistance performance is excellent. The fire resistance rating not only meets the requirements of international GB12666.6A 950 ℃ for 90min, but also meets the requirements of British BS6387-1994 for Grade A 650 ℃ 3hB 750 ℃ 3hC 950 ℃ 3h. At the same time, it can withstand water spray and mechanical impact during combustion.
2. Continuous length is long. Whether it is single-core or multi-core cable, its length can meet the needs of power supply length, and the limit length can reach 2000m.
3. The cross section of large single-core cable can reach 1000mm2 and the cross section of multi-core cable can reach 240 mm2.
4. With flexibility, the cable can be rewound on the cable reel with a bending radius ≥ 20D, and D is the outer diameter of the cable.
5, when burning smoke-free non-toxic, insulation using inorganic materials "non-burning body", combustion will not produce any harmful gases, but will not occur secondary pollution, can be called environmental protection green products.
If the cross-sectional capacity is too large, the cable not only has a large cross-sectional flow but also has a large overload capacity. According to the wiring requirements, the cable surface temperature is usually less than or equal to 70 ℃. If the wiring is not touchable and not in contact with combustible building materials, the cable sheath temperature can reach 105 ℃. The allowable working temperature of the fireproof cable can reach 250 ℃ when overloaded.
7, corrosion resistance, organic insulation fire-resistant cable sometimes need to wear plastic pipe or iron pipe, plastic is easy to aging brittle, iron pipe is easy to rust; fireproof cable is copper sheath does not need to wear pipe, copper sheath corrosion resistance is good.
8, no electromagnetic interference, fireproof cable and signal, control and other wires and cables are laid in the same shaft. Fireproof cables are shielded under a copper sheath. It will not interfere with the information transmitted by the signal? Control wire and cable.
9, good safety, fireproof cable in addition to the normal power supply in the flame, start fire extinguishing equipment, reduce fire loss. At the same time, it is also particularly reliable for personal safety. Its copper sheath is a good conductor, is a grounding wire, and is continuous to the full length of the cable, which greatly improves the sensitivity and reliability of grounding protection.
10, long service life, inorganic insulation materials, high temperature resistance, and not easy to aging, his life than the organic insulation cable increased many times?, in normal working conditions, its life can be equivalent to the building.

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.
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.
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.
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.
Low voltage power cable winter pay attention to matters? As the weather gets colder and colder, manufacturers of low-voltage power cables usually become more difficult, which brings inconvenience to construction. Here are some precautions for winter construction. Let us take a brief look.
