1- ABOUT R

MAGNET WIRE

“R

” is a registered trade mark of P. LEO & CO., LTD. and it is one of P. LEO’s high quality

products for electrical industry. “BC” means the best coating on magnet wire which will suit your

delicate designs. R

Research and Development (R&D) department is located in British

Columbia Canada where all R

UL recognitions are through P. Leo’s Canada office.. The

purpose of this brochure is to give you a basic picture of our wire and help you choose the most

suitable items.

Should you have any questions regarding ordering and engineering information, please contact our

experienced sales representatives.

1.1 Materials

1.1.1 Dimensions and resistance The conductor (copper), after insulation, will comply with the requirements given for

dimensions in Section 6 to Section 9. The resistance will be determined in accordance with

ASTM (American Society for Testing Materials) B193 and will not exceed 0.017241 ohm

(mm2/m)

1.1.2 Insulating materials Film or coatings will conform to the latest revisions of the applicable standards of ANSI,

ASTM, or NEMA. Various resins are referred in Section 2 as the basecoat and overcoat. The

resins specified may be modified. A modified resin is a resin that has undergone a chemical

change, or contains one or more additives to enhance certain performance or application

characteristics. But it will retain the essential chemical identity of the original resin and the

coated conductor will meet all specified test requirements of the appropriate NEMA standard

(for UL approved items).

1.2 Manufacturing

1.2.1 Application of insulation The wire will be coated or covered with a smooth continuous insulation and will meet

the thickness requirement as specified in later sections. Film covering will be smooth and

continuous, free from streakiness, blisters, and foreign material.

1.2.2 Intermediate sizes For wire sizes between AWG sizes, the increase in dimensions due to the film coating

will be the same as for the next larger size (AWG), and the test values will be the same as the

next smaller size (AWG).

1.2.3 Dimensions and metric equivalents In NEMA standards, units are expressed in customary British inch system. But their

approximate metric equivalents are included in later sections for your quick reference. For

indirect conversion of inches to millimeters, multiply inches by the factor of 25.4(exact). The

practice of rounding off numerical values is in accordance with ASTM E29.

1.3 Packaging The wire will be wound evenly and compactly on spools or reels, or will be deposited in

containers uniformly and compactly and free from kinks. The wire will be packed in such a

manner as to protect it from damage during transportation. You can find more details in

Section 11 and 12.

1.4 Order and Engineering Information 1.4.1 Orders magnet wire should include the following :

a. Quantity : Total number of Kilograms

b. Size : American Wire Gauge (AWG),

British Standard Wire Gauge (SWG),

Gauge (BWG) or equivalent diameters as a decimal dimension in

13- UL ELECTRICAL INSULATION SYSTEM In UL standard 1446, Electrical Insulation System (EIS)is defined as: “an intimate

combination of insulating materials used in electrical equipment. For example, the

combination of a coil form, separators, magnet-wire coating, varnish, lead-wire insulators,

and outer wrapping of relay coil”

13.1 EIS (Electrical Insulation System) Testing Qualification of an insulation system to either UL 1446 or IEC standard requires

testing of complete, assembled insulation systems. Electrical equipment manufactures are

faced therefore with testing the actual equipment substituting a motorette or

transformerette that represent their system; or using a recognized EIS through a material

supplier, Because final recognition of a system by UL requires that the system go through

5000 hr of heat aging at the lowest of the three or four temperatures the system is tested at,

many manufacturers choose the pre-approved system option.

The EIS test is composed of two test procedures, One qualifies the major

components of the insulating system by constructing the Test Rigs (Motorette) for

testing .The major components include ground insulation, magnet wire, intertwining

insulation, and varnishes, The dip varnish can be considered a minor component if the

motorette or transformerette did not use a varnish. The other procedure is called the

“sealed-tube testing” which is for the minor components of the insulating system such as

the tapes, lead wires, sleeving material and the dip varnishes.

The allowable magnet wire substitution in your UL Electrical Insulation System as described in next

page. e.g. If your EIS with MW28, it is also represent MW75, 79, 80, 82, 83.
