What does UL mean on wire?
What does UL mean on wire?
Underwriters Laboratory (UL) categorizes AWM as a Recognized Component used in Listed or Classified products. AWM is commonly used in a variety of applications such as general purpose wiring circuits, control circuits and internal wiring of appliances.
What UL 3271?
UL 3271 Hook-Up Wire UL 3271 is RoHS compliant and is primarily used for internal wiring of appliances, computers, industrial controls, military equipment, motor leads and transformers. UL 3271 wire has a temperature rating of +125°C and a voltage rating of 600 volts.
What UL 3321?
UL 3321 XLPE insulated hook-up wire is used for the internal wiring of appliances. Rated for 150C, 600VAC, and 750VDC.
What is VW 1 rated?
VW-1 is a vertical flame rating that measures the resistance of insulating materials to the propagation of a fire. The test involves mounting lengths of wire vertically in a ventilated chamber and attempting to ignite the wire with a gas flame.
What is UL voltage rating?
UL 1277, the standard for electrical power and control tray cable, was recently updated, allowing manufacturers with UL approved tray cable to market their product as 600V/1kV rated. To be dual rated, products must use a recognized 1kV rated conductor and pass a higher voltage AC Hipot test on the completed cable.
What is SFF 1wire?
Description of CSA SEWF-1, UL SFF-1: SEW-1 (SF1) and SEW-2 (SF2) wires consist of stranded, tinned or nickel-plated conductors with fibreglass over silicone rubber insulation. SEWF-1 (SFF1) and SEWF-2 (SFF2) are more flexible with a higher strand count.
What does VW-1 mean on a HDMI cable?
The VW-1 rating on this cable indicates that it complies with fire safety codes and insurance requirements and is safe for use inside the walls of residential class buildings.
What UL 1581?
UL 1581 is the Reference Standard for electrical wires, cables, and flexible cords operating in environments between 90°C and 105°C. This is the most widely used standard in North America for wire and cable, especially for temperature and FR ratings.
What does the data 300V 500V or 600V 1000V mean?
What does the data 300V/500V or 600V/1000V mean? These specifications describe the permissible nominal voltage of a cable, specified in volts. The first value is the maximum permissible effective value between conductor and protective conductor.
What is type SF wire?
SF-2 Apparatus & Motor Lead Wire is for use in lighting fixtures; high wattage units such as sun lamps and. therapeutic devises; control and power circuits, when high temperatures and abrasive environments are present. SF-2 is suitable for use in applications up to 200°C and 600 volts.
How do I tell if my HDMI cable is 4K?
If you want to make sure that your HDMI cable supports Ultra HD 4K resolution, you have to look for the HDMI High Speed logo on the cable’s packaging. This is what a typical High Speed label looks like. Some cables may have the High Speed label on them.
What is VW 1 cable used for?
VW-1: These cables have passed a VW-1 flame test and carry a “fire resistant” designation. The VW-1 test provides an assessment of the cable insulation material and resilience to fire. This is one of the most severe tests since it’s performed vertically and can be viewed as a worst-case test condition.
What UL 1015?
UL 1015 is an Appliance Wiring Material (AWM) style. Machine Tool Wire (MTW) is a completely different UL Standard that covers both wires and cables designed for use on industrial machines. This allows the hook-up wire to be used in applications that required either type of UL approval.
What UL 1569?
UL 1569 PVC insulated hook-up wire is used for the internal wiring of electronic equipment where it is not exposed to mechanical damage or movement. Rated 105C and 300VAC.
What does 300V 500V mean?
What does 300V mean?
If the applied voltage is AC, the rating is 300V rms. If the applied voltage is DC, the rating is 300V. If you look a few lines further down, you will see ‘withstand voltage 1500VAC (that is, 2120 peak) for 1 minute’.
What is SF 2 wire?
SF-2 Wire is part of Allied Wire and Cable’s extensive stock of high-temperature wire. SF-2 wire features stranded tinned copper conductors, silicone rubber insulation, and a fiberglass braid jacket. It may be used for motors or high-temperature lead wire.
What is PF cable?
Capacitance in cables is usually measured in pf/m (pico farads per meter) or pf/ ft (pico farads per foot). The lower the capacitance the better the cable performance.
