What are the Different Types of Electrical Wires used in Business?
The essential purpose of electrical wires is to enable power to be transported from the mains power supply to a device or piece of equipment. These are different to audio visual cables which transport signals between connect two devices that independently receive power through wire or battery.
How do electric wires vary?
An electric wire or cable is required for any application that needs power or lighting. As most businesses use powered machinery in some form or other, your business will likely require a range of electrical wires and power cables to perform. Different types of wires are applied in different situations according to voltage and current ratings. Safe electrical installation depends greatly on choosing the correct cable for the job. Electrical cable prices vary greatly according to sheath, the width and the core of the cable type.
Should I choose PVC or Rubber coated electric wires?
Electric wires are housed in mainly rubber, PVC or CPE sheaths providing a safe conduit for the electricity to travel. Polyvinyl Chloride (PVC) is a cost-effective product with a long lifespan. It is flame retardant and resistant to a wide range of chemical and oils as well as being abrasion resistant. These properties make it a safe housing material for the transport of electricity. PVC sheathed cables such as the H03VV-F (218-Y) are found in use for smaller household applications such as radios and lamps. The H05VV-F (318-Y) PVC sheathed cable is used for larger appliances like washing machines and refrigerators. Other uses include conveyor and lift equipment or panel wire that needs to withstand continuous and extreme high temperatures.
CPE (Chlorinated Polyethylene) as a thermoplastic jacket has superb oxidation, flame retardation and is resistant to heat, oil and weather making it a favourite in industrial wiring.
Rubber cable sheaths are also still used and provide safe handling for a range of wiring such as the heavy duty H07RN-F for indoor and outdoor environments and the submersible H07RN8-F cable for underwater applications up to 10 metres. Other types of sheath include the spiral structured curly flux which is utilized as an extendable mains cable and fixed wiring cables for different uses.
What is the core of a cable?
The core refers to the copper wires inside the cable. Cable sizing refers to the cross sectional area of the cores, which relates to how much current flows through them. Power circuits typically use cables that contain 2.5mm2 cores while a cable that holds 1mm2 cores is applied to lighting circuits.
The most common terminology in reference to cores is twin core which is used for auxiliary power, electric brake controllers and trailer or caravan wiring and earth core which allows the current to flow to the ground on the chance that a fault develops.
To ensure the safe installation and application of electric cables, be sure to talk to an expert about the types of electrical wire, including voltage and core, that your business requires.
