In order to protect the home appliances and electric equipment from heavy damage and to ensure highest possible safety requirements, extension cords are being used widely in domestic and commercial appliances. Based on the functionality and purpose of use, extension cord and relays are similar. Extension cord helps in isolating the equipment and thus acts as circuit breakers. This type of protection ensures the reliability of continuous power supply and also allows for more than more load to be connected. An extension cord has essentially two components. One component involves the fuse and switches that allows the passage of current and the other is the control system or control panel that monitors and controls the fuses. In earlier days, switchgears were mounted on the wooden panels. Due to the safety and other concerns like susceptibility and life, modern switchgears are made to be weatherproof. There are number manufacturers and distributors of switchgear with varieties of designs. One such distributer of extension cord is direct wholesale suppliers, who are notable for their assured quality and affordable price.
Varieties of extension cord
Extension cord is available in various types such as, air insulated, gas insulated and solid insulated cords. With the need for new technology, switchgear made with solid dielectric materials has been introduced. This is combined with vacuum technology that provides insulation and compact design. They are designed based on the voltage consumed by the appliances as, low voltage switchgear, medium voltage switchgear and high voltage switchgear. Some extension cords are enclosed inside weatherproof housing for the equipment’s involved in outdoor use. Extension cords find its application in overhead lines, transformers and in industries using arc furnaces and so on. Domestic extension cords are available based on the current rating involved with the appliances. Making use of online source, there is chance for you to buy the quality extension cords for affordable cost.
