Using the lighting cable supply interior and exterior lights. It generally includes elements such as copper or aluminum drivers, insulation, a sheath and connectors.
It is commonly used for various lighting equipment inside and outside the buildings, such as lamps, LED lamps, projection lamps, etc.
Moreover, The lighting cable can be used outside for a long time, which is suitable for road lighting, places, parking lots and other places.
Presentation of lighting cables
THE lighting cables are cables used for lamps and lanterns, Including lamp leader and lamp cables. Generally speaking, The lighting cables are more flexible and finer, with higher insulation resistance and fireproof properties.
While ordinary cables are generally used to transport electrical energy, They have a greater number of souls and greater density between souls.
Lighting cable structure
The lighting cable is relatively simple, generally with a unipolar or bipolar structure, The diameter of the wire is fine, The outer layer is generally in PVC. The ordinary cable, as for him, consists of a bundle of several drivers, The number of diapers, The diameter of the wire is thicker, The outer layer is generally in PE.
The soul is generally made up of a copper wire, which has better flexibility and better conductive efficiency.
Depending on the total power of the power line, It is possible to choose a different radius for the soul.
Lighting cable types
Depending on the intolerable structure of the cable, We can distinguish BV types, BVR, BVV, RVB, RVS and other types of structure.
BV
The BV cable is a cable with a copper soul isolated with polyvinyl chloride. Its central driver is a simple naked copper wire with a rigid soul that can be folded directly to facilitate installation. The exterior is wrapped in a polyvinyl chloride insulation.
The BV wire has good structural resistance, Installation requires the use of folding tools, good resistance to high temperatures and high safety.
The wires are thicker and have better conductivity, which makes it possible to meet the needs of high power devices.
It is used for the wiring of domestic circuits, Including interior power supply, lighting of lamps and lanterns, Power sockets and other domestic wiring connections.
BVR
The BVR is a flexible thread with a copper soul isolated with polyvinyl chloride, which can be divided into a wire delayer of flames (Zr-bvr) and in fire resistant thread (NH-BVR) Depending on the material used.
The structure of the BVR and the BV is similar, Its central driver consists of several torthus copper wires together, with a more flexible soul to facilitate folding. The exterior is wrapped in polyvinyl chloride insulation.
The BVR has good electrical conductivity, good flexibility, high temperature resistance, Corrosion resistance, Due to the relatively fine soul, It is generally used for low -voltage lighting cables.
BVR wires have good flexibility, are easy to fold, go through the pipe, are suitable for small spaces or mobile electrical equipment.
They are also suitable for the part of the domestic lighting line which must be more folded and the part of the equipment which must be moved frequently.
BVV
The BVV wire is the full name of the pvc wire wire with copper soul. The BVV structure includes, from the outside, The copper soul, insulation and outdoor sheath, which can be considered an enveloping sheath more than a bv wire.
Compared to BV wire more than one layer of exterior PVC sheath, It is no longer necessary to wear a wire hose or groove, which improves security and convenience. At the same time, It has antacid and alkaline characteristics, anti-humidity and others.
BVV lighting wire is generally used inside, especially for household appliances, Interior decoration, lighting equipment, Small devices and certain instruments.
RVB
The full name of the RGB wire is a flexible flat connection wire isolated in PVC with copper soul. This is a kind of soft flat wire without sheath, which is extruded by a red copper wire and a black copper wire isolated parallel.
Structure simple, internal use of a copper core, external use of polyvinyl chloride as insulation.
It is generally used for the internal equipment circuit of equipment, such as household appliances, Small electric tools, electric lighting.
RVS
The RVS thread is a thread tortured in pvc with copper soul. The structure is similar to that of RGB, with a copper soul inside and PVC insulation outside. It consists of two twisted threads together.
Domestic lighting is suitable, to household appliances, to wiring electrical tools and fire alarm devices.
Lighting cable applications
Due to the limited field of application of lighting cables, These are generally used for interior lamps and outdoor lighting equipment, such as spotlights, The ceiling lights, Chandeliers, Outdoor lampposts, Light display panels, etc.
Lighting devices generate heat during use and, from a security point of view, They require high insulation resistance and fireproof properties.
At the same time, in order to guarantee security and compliance with standards, It is necessary to follow certain specific standards.
Interior lighting
The transmission power of lamps and lanterns being relatively low, The unipolar lighting cable is generally sufficient. It should be noted that during the use of the light source and the current, heat is produced, and that cable temperature resistance is subject to certain requirements to avoid accidents during use.
Road lighting project
Road lighting is considered a lamp and a high current lantern, There are more other components that generate more heat, It is therefore necessary to ensure the quality of these accessories to avoid the impact on the cable insulation layer.
Road lighting will be crossed by a higher current, The electrical properties of the lighting cable have higher requirements, It is therefore necessary to pay attention to the transport capacity of the cable current, insulation resistance and electrical properties. Cables with a larger driver section are generally used, the resistance of the insulation and the electrical properties must be taken into account.
Steps of using lighting cables
The installation of lighting cables has several steps, in particular the selection of materials, Line design, Preparation and installation. Here is an overview of the detailed process :
Wire selection : The lighting wire is selected according to the total electricity consumption of the line and other requirements for wiring. Once the wire is determined, You must prepare wire connectors and other protective materials.
Line design : In line design, User needs and ease of use are prerequisites, Depending on the type of lighting line design, including the right part, The curved part, The line through the pipe, The chute line, etc.
Preparation : Clean the installation line to make sure that there are no obstacles when laying cables. Check the wire specification parameters and the external structure to ensure the quality of the cable.
Pose cables : The cable installation process must be supervised on site to ensure that the line is placed in accordance with design specifications.
Cable protection : The cable installation process aims to protect the line, in order to prevent other factors from interfering with the installation process and leading damage.
Tests and debugging : After completing the laying of the line, It is advisable to carry out tests and unlocks to ensure that the line is working properly.
In the properly said installation process, but also depending on the environment and specific installation requirements, It is necessary to follow the relevant standards and standards to protect the quality of the project and meet the needs of users.
