With the increasing popularity of social intelligence, modern wiring, like the human nervous system, extends to every corner of the building, full of dense cables, especially like the data center and skyscraper infrastructure under construction, the number of cables they carry is even more amazing. Every time you do a project, you will only think: how many kinds of cables and meters will be used in this project? There are many types of wire and cable, but their fire resistance and flame retardant requirements have been ignored and become a huge fire hazard. Therefore, several elements of wire and cable fire resistance and flame retardant rating should be considered in engineering design.Yanggu Power Cable Manufacturer,Yanggu cable manufacturerSome reference suggestions are provided:

Cable laying environment
The laying environment of the cable largely determines the probability of the cable being attacked by external fire sources and the possibility of disaster caused by delayed combustion after fire. For example, non-flame retardant cables can be used in direct buried or separately penetrated pipes (metal, asbestos, cement pipes), but they can also be placed in semi-enclosed bridges, trunking or special cable trenches (with covers), which can reduce the flame retardant requirements by one or two levels. It is recommended to use flame retardant C or flame retardant d
Because in this environment, the possibility of being attacked by external factors is very small, even if the combustion is blocked by the narrow water in the space, it is easy to extinguish by itself, and it is not easy to cause disasters. On the contrary, if it is exposed indoors, or it is easy to reach the tunnel, interlayer, tunnel corridor or pedestrian fire, the flame retardant rating should be moderately increased.Yanggu Cable FactoryIt is recommended to choose flame retardant Class B, or even flame retardant Class A

When the above-mentioned environment is before and after the high-temperature furnace or in the flammable and explosive chemical, petroleum and mining environment, it must be strictly handled and cannot be too high.Yanggu Cable FactoryIt is recommended to use flame retardant Class A or halogen-free low-smoke flame retardant Class A.

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.
