Building & Construction Cables

Building & Construction Cables

As an integral part of building electrics, wire and cable are used in a wide range of applications.
With the increasing electrical load in buildings, electrical fires caused by burning cables also occur frequently.
At the same time, once a fire occurs, the safe and reliable operation of fire-fighting equipment also requires the protection of wire and cable.
Therefore, the choice of building electrical wire and cable, is not only related to the normal use of electrical equipment.
But also related to the construction cost of building electrical, and more importantly, related to the safety of electrical use, and even the personal safety of the building personnel.

Commonly Used Wires and Cables for The Construction

1. Ordinary Cables

Mainly refers to polyvinyl chloride insulated wire BV wire and cross-linked polyethylene insulation(PVC insulation) polyvinyl chloride sheath insulated power cable YJV.

2. Flame Retardant Cables

Difficult to catch fire and can stop or retard the spread of flame wire and cable. The cable usually refers to the GB/T18380.3 (equivalent to IEC60332-3) test qualified wire and cable.
Including fire-retardant polyvinyl chloride insulated wire ZRBV wire and fire-retardant cross-linked polyethylene insulation polyvinyl chloride sheath insulated power cable ZRYJV.

3. Fire-Resistant Cables

At the specified temperature and time of flame burning, still, maintain the integrity of the line wire and cable. Usually refers to the GB/T12666.6 (equivalent to IEC60331) test qualified wire and cable.
Including fire-resistant polyvinyl chloride insulated wire NHBV line and fire-resistant cross-linked polyethylene insulation polyvinyl chloride sheath insulated power cable NHYJV.

4. Low-Smoke Zero Halogen Cable (LSZH Cables)

Halogen-free low-smoke flame retardant cable WDZ-BYJ/YJY: the material does not contain halogen, less smoke, and dust generated when burning, and can stop or delay the spread of flame wire and cable.
Usually can pass GB/T 17650.2 (equivalent to IEC60754-2), GB/T17651.2 (equivalent to IEC61034-2), and GB/T18380.3 (equivalent to IEC60332-3) three standard test qualified wire and cable called halogen-free low-smoke flame retardant wire and cable.

5. Mineral Insulated Cables

Mineral (such as magnesium oxide) is the insulation material of the cable. Usually composed of copper conductors, mineral insulation, and copper sheath does not contain organic materials.
And has non-combustible, smokeless, non-toxic, and fire-resistant properties.

The Selection and Laying Requirements of Wire and Cable In Residential Buildings

The selection of wire and cable in residential buildings, mainly concerning the “Residential Building Electrical Design Code” and “Civil Building Electrical Design Code” in the provisions.

Distribution Line Laying Requirements

The choice of cable laying method should be selected according to the engineering conditions, environmental characteristics and cable type, quantity, and other factors, as well as to meet the principles of reliable operation, easy maintenance, and technical and economic rationality.

In the building electrical design, first, we must fully understand the characteristics of wires and cables, and correctly distinguish the importance of the building, special features, and fire hazards. According to the different buildings, different parts, and different supporting equipment choose its corresponding wire and cable. The correct choice of wires and cables can not only meet the normal use of buildings and ensure the safety of personal property but also meet the building’s electrical energy saving and reasonable cost.
