Copper and copper coils munificently meet the modern life challenges. It makes a great metal choice for many operations that involve electricity. You might have noticed copper as custom coils in plumbing systems and inside electro-mechanical assembly of many types of equipment in offices, houses, industrial and commercial buildings. Coils of copper are invariably the most essential material to keep commerce, industries and home running efficiently and safely.
Copper works wonderfully in solenoid due to its low electrical resistance and for same reason it is preferred for many other equipments such as in refrigerator, space heaters, big industrial machines etc. It is predominantly found in many heating, engineering, cooling electrical, refrigeration and heat exchange applications because of following main reasons: ,
- Copper is a better conductor of electricity than other metals
- Copper can easily be cut and molded varied shapes and sizes
- Based on its application, copper can be transformed into pipes, plates, rods, coils and sheets etc
- Copper is highly energy efficient. An appropriate use of one ton copper in energy department can reduce emission of carbon dioxide by 200 tons on an average in a year
- Copper is long lasting, naturally good in looks and 100% recyclable
Modern Life Applications Of Copper
Copper makes modern life running through many of its applications in construction, transport and electrical applications. Let’s explore how…
A well over 65% of total copper production is used in electrical applications. As already stated, it provides highest unit of electrical conductivity and thus it makes an ideal material for electrical, power generation and transmission equipments.
- For power generation and its transmission copper is used in generators, motors, transformers, cables and busbars for safer electricity delivery to many offices and homes.
- For a variety of electrical equipments, copper provides wiring, contacts and circuitry in televisions, computers and even mobile phones.
Transport industry accounts for a usage of copper that is over 7%. It is used in cars, trains, lorries and trams. The systems harnessed with copper wires and coils carries current from batteries to entire vehicle and apparatuses such as central locking, lights, satellite navigation systems and on-board computers. It also helps in Eco friendly and efficient transport systems.
Over 25% of copper production is effectively used in buildings for cladding, roofing and plumbing. Since copper is light weighted maintenance free and highly durable, it makes a preferred choice of the construction industry. Its antimicrobial properties are best exploit to make hygienic surfaces in healthcare facilities and hospitals.
Other Uses Of Copper
Apart from being used to produce latching solenoid, solenoid valve and push-pull solenoid, a large percentage of copper is used to make coins, musical instruments, cookware, sculptures and fashion jewelry.
Copper coils resourcefully to serve many modern life functions more energy efficient and safe.
Solenoid is derived from the Greek words ‘solen’ which means a pipe or a channel and ‘eidos’ which means form or shape. A solenoid is simply a coil which is wound in tight helix. A solenoid essentially consists of a wire which is wound around a solid steel and iron. When current is passed through such a coil it becomes electromagnetically charged such that the movable core draws into the coil when current flows and it is this principle that is used for making a switch or in case of a mechanical device, a valve.
The applications of solenoid are immense and just some of these have been enumerated below.
Commercial appliances: Valves are essentially switches, the only difference being while the former controls mechanical devices the latter controls electrical devices. These solenoid valves therefore control the flow of hydraulic fluids and they often operate at pressures of around 3000 psi. These solenoids control the movement of oil to the actuators or rams. Such types of valves are often used in irrigation systems and also in our household appliances like the washing machine where they control the flow of water.
Automobile Industry: Solenoid is an integral part of the automobile ignition and starter system. Normally the starter solenoid receives very small current from the ignition and a very large current from the car battery. The moment you turn on the ignition switch pair of heavy contacts in the starter solenoid are closed thus allowing the larger current from the battery to flow. Often starter solenoids are built on the starter itself.
Electromechanical solenoids: They consist of an inductive coil which is electromechanical and wound around an armature. The coil is so wound so as to enable the armature to move from its mean position and thereby becoming an electromagnet by altering the coil’s inductance. This armature then provides the mechanical force necessary to move a mechanism for example a valve. The advantage is that they have a very short reaction time. Electromechanical solenoids are commonly used in pinball machines, fuel injectors, and dot matrix painters.
Security: Many automatic systems today incorporate solenoids. When in a locked position the solenoid does not consume power, however it needs a small current to unlock therefore some solenoids also incorporate battery packs. They are installed in high security areas, factories and offices.
Medical: With the advent of modern electronic machines, solenoids have increasingly become an important part of the medical field. They form an essential component of the dialysis machine, with a pair of two solenoids the dialysis machine controls the blood flow. A dosing machine which is used to ingest medicine into the blood flow also uses solenoids.
