What is Copper Clad Aluminum Wire ?
Magnet wire is an insulated copper or aluminum conductor used to wind motors, transformers, generators, and any other electrical equipment that converts electrical energy into mechanical energy.

The insulating layer can be a layer of varnish (enamel) or some type of covering; such as polyester glass, mica or polyimide tape. Insulation provides electrical or mechanical properties to the wire.

What is winding?
Winding wire is another name for enameled wire. Winding wire is commonly used in Europe and Asia, while enameled wire is more commonly used in North America.

What is an insulating structure?
The insulating layer is the amount of enamel or coating added to the circumference of the wire. There are four different insulation structures for enamel: single-layer, heavy-duty, three-layer and four-layer. There are many build variants available for other product lines.

Why are there different builds?
The insulation structure is directly related to the required dielectric strength or the required degree of mechanical protection.

What does AWG stand for?
AWG stands for American Wire Gauge, which is used to identify the diameter of round wires.

Does the rectangular wire have AWG size?
no. AWG refers only to round wires and square wires.

What does NEMA stand for?
NEMA stands for National Electrical Manufacturers Association. NEMA is the trade association of choice for the electrical manufacturing industry. The NEMA 1000 standard defines product standards for the enameled wire industry.

What does ASTM stand for?
ASTM stands for American Society for Testing and Materials. ASTM International is one of the world's largest voluntary standards organizations, providing technical standards for materials, products, systems and services.

What does IEEE stand for?
IEEE stands for the Institute of Electrical and Electronics Engineers. It is an organization that provides technical and professional information for the electrical, electronic, and aerospace industries.

What does UL stand for?
Underwriters Laboratories. It is an independent product safety certification body.

What does level 200 mean?
Class 200 is a wire designated by IEEE, which can operate for 20,000 hours at a "continuous operating temperature" of 200 degrees Celsius. Craig Wire's CW 200 is an example of a 200-class wire.

What does class H mean?
This is the alphabetic name of the 180 category.

What are 155 level and F level?
These are the names of magnet wires, which can operate for 20,000 hours at a "continuous operating temperature" of 155 degrees Celsius. Examples of products in category 155 are CW Mica and CW DPG.

Can I buy category 240 wire from CWP?
Yes. Craig Wire's CW 240 TP is a class 240 wire wrapped with polyimide tape.

Why use flat wire instead of round wire?
Rectangular wires allow engineers to design motors with more copper in a unit. The round wire has more space between the wires in the winding.

Does enameled wire have a shelf life?
Enameled wire has no shelf life, except for mica-coated enameled wire.

Does enameled wire need special storage conditions?
No, it is not. However, rectangular and square wire reels should not be stored on their side.

How many 24-inch reels are on a pallet?
A standard tray with 24" x 6" reels will have 2, 4 or 8 reels.

A standard tray with 24" x 12" reels will have 2 or 4 reels.

How much does a 24 inch rectangular wire roll weigh?
The average weight of a 24 inch x 6 inch reel is 250 pounds. The maximum weight on the reel is 350 pounds.

The average weight of a 24" x 12" reel is 500 pounds. The maximum weight on the reel is 650 pounds.

If I can buy 80-pound round wire in reels and barrels, why should I choose one instead of the other?
The reel is more suitable for high-speed winding applications. Barrels in high-speed winding applications have a tendency to become tangled. The bucket is best used in a repair shop where high-speed winding is not a problem. In addition, after the electric wires are used up, the barrels are used for practical purposes in shops.

What is a "whisker disk"?
The "whisker disc" is a disc with plastic filaments (whiskers), which is placed on the flange of the reel to increase the tension during the pay-off to control the withdrawal.

Can I buy rectangular wire in barrels?
Do not
