Safety considerations

The wire is no harm to inhalation and skin contact. But if the insulation film is decomposed, the decomposed components have harm to inhalation and skin contact. So, please use the wire under consideration to the following points:
(1) Avoid to ignite by fire, static electricity, spark and so on.
(2) Don’t mix peroxide, strong acid, strong alkali, strong base and other oxidizers.

(3) Use ventilation system or removing the insulating film of the wire by chemicals, solders, etc. not to inhale harmful decomposed gas. And use gloves not to touch the chemicals, solders, etc.

(4) Scrap by suitable burning or burying.

 

CONSIDERATION ON WINDING COIL

(1) General Attention

The wire shall be used for winding electrical coils. For the other purposes, the wire shall be evaluated by suitable procedures. And also, please check the wire on the following points before use.

a) Label Please check the label of the wire to prevent wrong use. And please record the production code of the wire to trace the production record of the wire.

b) Dimensions Please check the conductor diameter, film thickness and overall diameter fo the wire to prevent wrong use.

c) Appearance Please check appearance of the wire to find damages, dust and dirty on the wire under handling and storage.

 

(2) Attention on Wire

Please handle the wire with care considering the insulation film of the wire is very thin and easy to be damaged by sharp edges of tools and so on. Especially, please use the wire with consideration on the following points.

a) Winding Tension

Winding tensions shall be selected with consideration on the reduction of properties after elongated due to the reduction of dimensions and the remained stress. Maximum 5% elongation shall be recommended to keep original properties.

b) Handling Terminal

Terminals of coils have sharp edges and make damages on the other wire and so on. Please handle the terminals with care.

In case of soldering and connecting terminals, please consider the conductor of the wire after removing the insulating film is easy to be oxidized

 

CONSIDERATION ON MAKING COIL

(1) Attention on Mold for Making Coil Please check the appearance of the mold for winding coils before winding to prevent to make damaged on the wire. And also, please check the dimensions of it to prevent to make the different coils.

(2) Attention on Applying Tension Tension shall be applied to the wire in the process of winding coils. Please apply tension by pulleys to prevent to make the wire damages, don’t apply tension by strong press the wire with flat plates and rollers. In applying tension, please consider to minimize the elongation.

(3) Attention on Winding by automatic machine Normally, automatic winding machines easily make the wire damages due to hard vending and much tension. In winding by machines, please evaluate by checking properties of the wire after winding..

(4) Attention on Repairing Insulation Normally, repairing the insulation film shall not applied. But in necessary case, repairing materials shall be same as the insulation of the wire.

(5) Attention on Removing Film Removing the insulation film of the wire shall be applied for connecting terminals in the process of making coils. In case of chemical removing film chemicals shall be applied to terminal wire with considering not to stick on the other positions. And after removing the film, chemicals on the wire shall be neutralized by other chemicals, applied water to remove chemicals and wiped by clean cloths to prevent remained chemicals remove the other insulation film and corrode to break the wire. And also, please use safety glasses, gloves and clothes in the proves of removing film to prevent connect to eyes and skin. In case of mechanical removing film, please consider not to make damages on the wire, to remain copper powder on the wire and not to reduce the conductor diameter too much .

(6) Attention on Soldering Soldering shall be applied to remove the insulation film of the wire and connect to terminals. Please solder with suitable conditions not to reduce the conductor diameter too much and not to reduce the original properties of the wire. And also, please consider not to stick the solder on the insulation film of the wire.

(7) Attention on Handling Coil Please consider handling not to make damages on the wire and avoid dust, metal powder, water, solvent and sun beam to keep the properties of the wire.

(8) Attention on Dipping Varnish Dipping varnishes and conditions shall be selected not to reduce the original properties of the wire. In the process of dipping varnish, please consider no heating coils before dipping can not remove the stress in the insulation film of the wire after winding, and also can not remove sweat and humidity. So, heating coils before dipping varnish is recommended to keep the original properties of the wire.

 

CONSIDERATION ON STORAGE

(1) Attention on Storage Condition

a) Avoid sun beam

b) Avoid high humidity

c) Avoid solvent, gas, and so on

d) Avoid dust and metal powder

e) Prevent to make damages on the wire

(2) Storage Limit

The properties of the wire under the above condition shall not be changed more than 10 years. But if storage condistion is not so goods, the properties shall be sharply down. So, after keeping 1 year, please use after checking the properties of the wire.

 

OTHERS

(1) Chemical substances controlled in the Japanese law shall be used in the wire.

(2) Ozone layer destructive substances shall not be used in the wire.

(3) Bromic non-inflammables shall not be used in the wire.
