We’re all aware of the impact single-use plastic is having on our oceans, but did you

We’re all aware of the impact single-use plastic is having on our oceans, but did you know that clothes release half a million tonnes of microfibres into the sea every year? That’s the equivalent of more than 50 billion plastic bottles – and these small plastic fibres have even been found sealed in Arctic ice. #SecondHandSeptember, a campaign run by Oxfam encouraging people across the UK to stop buying new clothes for the month in a bid to cut back on fast fashion, is in full swing. But, it’s also important to check labels to see what our clothes are made from when shopping. This is because some fabrics have a higher environmental impact than others. Here, George Sullivan, CEO of The Sole Supplier, reveals the five fabrics that have the biggest impact on our oceans – along with the switches you can make to shop with the planet in mind. “Polyester is a type of plastic derived from petroleum and is used to make seatbelts, tents, carpets and yes… clothes,” George explains. “As well as being cheap, polyester clothing is often non-iron and quick-drying making it perfect for busy lifestyles. However, as a manmade fabric, it doesn’t come without its...

Capacitors Execute Three-Phase AC-Power Harmonic Filtering

This site is operated by a business or businesses owned by Informa PLC and all copyright resides with them. Informa PLC’s registered office is 5 Howick Place, London SW1P 1WG. Registered in England and Wales. Number 8860726. The Type PFCH capacitor series from Cornell Dubilier Electronics, intended for the ac output of large inverter systems, filter undesirable harmonics before power is delivered to the grid or load. The three-phase, ac-power, harmonic-filter capacitors are fabricated with three self-healing metallized polypropylene windings, connected in delta, and enclosed in a cylindrical aluminum case filled with environmentally friendly fluid. Built-in bleeder resistors reduce voltage to safe levels when capacitors are taken offline for maintenance. At end of life, a UL810-approved internal mechanical pressure interrupter disconnects the capacitor winding from the circuit before pressure exceeds unsafe limits. PFCH ratings range from 0.5 to 17.5 KVAR at 240 V ac; 0.5 to 30 KVAR at 480 V ac, and 1 to 25 KVAR at 600 V ac. Case sizes range from 2.0 to 3.5 in. in diameter; lengths extend from 5.75 to 13.73 in. Applications include automated power-factor-correction equipme...
