Insulation Wires for Electric / Electronic / Communication Equipment(Sheath (outer coating) color:Brown)
Insulated wires for electrical, electronic and communications devices supply power to general households and factories, electrical and electronic components in large machinery and communications devices. The wires are made of drawn copper, copper alloys, aluminum, etc., and are used to connect and conduct electricity between 2 points. These wires feature conductors made of copper, etc., covered with an insulator. The wires are classified into insulated wires that transmit high current and those that transmit low current, with insulation material made of vinyl, PVC, polyethylene, etc. Some insulated wires feature fluoropolymer and polyester materials. Some insulated wires also feature a protective coating on top of the insulator.

Question: How many types of wires are there and how to choose the right wires?
Answer: Cable can be separated into 2 types.
1. Low voltage cable which using for electric system with voltage 750V or less. Typically, this type of cables is made of copper or aluminum such as THW, VAF, VCT and NYY.
2. High voltage cable which using for electric system with voltage 1kV-36kV, conduct structure are stranded wire such as Aluminum Conductor (AAC), Aluminum Alloy Conductor (AAAC), Aluminum Conductor Steel Reinforced (ACSR), Partial Insulated Cable (PIC), Space Aerial Cable (SAC), Preassembly Aerial Cable (PAC) and Cross-linked Polyethylene (XLPE)
Cable should select based on using electrical voltage and current. Moreover, we should select cable insulation which suit for operating environment such as Heat resistance, weather resistance or chemical resistance.
Question: What are the components in the cable?
Answer: Cable components are consisting of 3 parts as below.
1. Conductor
Made of metal wire, use for transmitting the electricity.
2. Insulator
Insulator is the component which is cover conductor wire to block electricity from conductor transmit to another part.
3. Sheath
The outer cover of cable use for protecting any harm to cable inside such as scratch, weather, and heat.
Question: What types of wires are used in households?
Answer: Cable for home appliance is low voltage cable type which is applicable for voltage 750V or less such as,
1. THW cable, which consist of solid-core conductor wire with PVC insulator. Suit for wiring inside the building.
2. VHF cable, which consist of multiple solid-core conductor wire with colored insulator inside white sheath. Suit for wiring inside the building.
3. VCT cable, which consist of multiple stranded conductor wire with insulator inside the black sheath. Due to, heat and water resistance properties, this cable can be wiring outside the building. However, it cannot not wire directly underneath the ground. I should wire through electrical conduit pipe.
Question: What applications are 1.5 mm wires suitable for?
Answer: 1.5 mm2 is suit for general electrical home appliance which using current not exceed 15A and power does not exceed 3.5 kW.
Question: Why are there different colors of wires?
Answer: Electrical wires are identified by their insulating casings. To identify wires quickly and easily, nearly all electrical and electronic devices use color-coding.
A live or hot circuit is typically black or red, but yellow or blue are also suitable.
Neutral wires can be gray or white.
Ground wires can be green, green with yellow stripes, or bare copper.
Due to the colors' variability, learning the ropes can be confusing. When installing a new light fixture or during a blackout, you might find it helpful to know the meaning of the colors. Electric wires carry high voltages that may cause injury if you are not careful.
