What is XLPE SWA LSF?
SWA XLPE LSF Cable
Suitable for both indoor and outdoor use, this armoured cable is XLPE insulated and LSOH bedded, with a tough steel wire armour and an LSOH sheath.
What is XLPE LSF cable?
The power and control cables with insulation of cross-linked polyethylene (XLPE) type LSOH are flame retardant, with low halogen free smoke emission and corrosion at fire conditions and are suitable for use in electrical installations for nominal voltage Uo/U 0.6/1 kV.
What is CU XLPE SWA PVC?
Standard Armoured – IEC 60502-1. Application. Cable for power supply, for rated voltage up to 0.6/1kV. Suitable for outdoor fixed installations when it is necessary to protect the cable against mechanical aggression or against rodents threat.
What does LSF cable mean?
Low Smoke & Fume
LSF (Low Smoke & Fume) Cables
LSF cables are usually made up of a modified PVC compound which produces somewhat less HCL gas and smoke on burning than PVC.
What’s the difference between XLPE and PVC SWA?
XLPE is crosslinked polyethylene. PVC is polyvinyl chloride. The key difference between XLPE and PVC is that XLPE has crosslinks between polymer chains whereas PVC has no crosslinks between polymer chains.
What is the difference between LSF and PVC?
LSF SWA Cable is a similar type of armoured cable, the only difference being the outer cable sheath. It’s constructed different to regular PVC, meaning the sheath is ‘Low Smoke & Fume’ (LSF). This means that when burnt, the cable lets off less harmful smoke and fumes which allows people to exit the building safely.
Is XLPE cable Armoured?
XLPE cable means cross linked polyethylene insulated aluminium conductor armoured cable.
What is CU XLPE PVC cable?
The power and control cables with cross-linked polyethylene (XLPE) armored with galvanized steel wires are used in electrical installations with nominal voltage Uo/U 0.6/1 kV. These cables are used in industrial installations and urban networks.
Where is LSF cable used?
LSF/LSZH cables are popular in places where people live close to cable assemblies and cannot get sufficient ventilation during the fire. These cables find vast application in skyscraper, malls, large commercial spaces, military, railroad, maritime and aerospace.
Do you have to use LSF cable?
The use of LSOH cables is not a requirement of BS 7671 in domestic or Non-domestic buildings at present. The use of these cables is often subject to specification requirements rather than regulation. Regulations, however, may soon require such cables when installed in escape routes in certain buildings.
How do I know if my cable is XLPE?
You can usually tell by looking at the bedding around the insulation. XLPE has a softer, peelable appearance. Typically PVC is always black. XLPE is often white, grey or black.
What is SWA PVC cable?
The range of hard-wearing steel wire armour (SWA) and aluminium wire armour (AWA) XLPE insulated cables is manufactured in accordance with IEC 60502-1 and is designed for use in applications where there is a risk of mechanical stress and where protection is required against mechanical damage.
What is PVC SWA?
Why XLPE is used?
What are the benefits of XLPE? XLPE insulation performs at both high and low temperatures. Due to its structure, XLPE is extremely resistant to abrasion and other wear and tear. It also boasts resistance to high voltage electricity, chemicals, and other hazardous materials.
Where is XLPE cable used?
Common applications of cross-linked polyethylene (XLPE) are in building plumbing (or pipework) systems, as insulation for high voltage cables, and as an alternative for polyvinyl chloride (PVC) and copper tubing in water pipes.
What is CU PVC?
Copper (plain annealed): solid class 1 or stranded class 2 or flexible class 5, circular or sector shaped. Insulation. PVC – (Polyvinyl chloride) Oversheath. PVC – (Polyvinyl chloride)
Is PVC cable LSF?
LSF Cable is manufactured from PVC. These cables can give off a thick black smoke and poisonous fumes when burnt as they are made up of a modified version of PVC. The amount of PVC present in these cables can differ from manufacturer to manufacturer which makes installing LSF Cables in public places a complete gamble.
Do I need an LSF cable?
What is LSF protection?
LSF is an abbreviation for “sun protection factor”, which is also known as SSF, IP or SPF. It indicates how much longer you can stay in the sun without a sunscreen. A person with skin type I and a self-protection time of 10 minutes may be using a sunscreen with SPF 30.
What wiring type is SWA?
What is an SWA Armoured Cable? Commonly known as SWA cable, the steel wire armoured cable is a power and auxiliary control cable, designed for use in mains supply electricity. Used for underground systems, cable networks, power networks, outdoor and indoor applications, and cable ducting.
Is XLPE waterproof?
In order to prevent the penetration of moisture and also to extend the duration of life, the XLPE insulated medium voltage cables are designed with longitudinally waterproof shielding including an additional swell tape and PE outer jacket.
What is 4 core electrical cable?
4 core cable consists of four individually insulated wires that are together protected by an outer PVC coating or sheath. It is available in a range of types and lengths, and is most commonly used in low-voltage, low-transmission installations such as extractor fans that are controlled by PIRs or humidity detectors.
What type of copper is used in electrical wiring?
The main grade of copper used for electrical applications is electrolytic-tough pitch (ETP) copper (CW004A or ASTM designation C11040). This copper is at least 99.90% pure and has an electrical conductivity of at least 101% IACS.
What is LSF material?
What are LSF Cables? LSF stands for “Low Smoke and Fumes.” This type of cable is made up of PVC compound that has been modified to decrease the amount of gas and smoke that is produced when burning compared to traditional PVC designs.
Why is SWA cable used?
The SWA Cable is designed to have mechanical protection, which is why the cable is often used for external use. The armour is used to reduce any risk of the cable getting pinched or damaged; the steel is used to protect the armoured cable.
