Specifications of Pre-insulated Copper Foil:
Copper foil laminated with polyester (Cu-PET) has higher conductivity and electromagnetic insulation. High quality anneal copper foil laminated
with polyester film by using a unique glue formula provides above 15% elongation. Mainly used for coaxial cables, signal cables, control cables,
data cables, instrumentation cables and other communication cables that require higher shielding insulation.
1) Standard: Regard of different insulated coating material, the thermal endurance class are B, F, H in according to RoHS-2002/95/EC
2) Delivery State: With 100 and 200m copper foil round on the inner diameter of 76mm coil core
3) Storage Condition: No more than 6 months, under the dry and cool environment condition about 20℃
4) Technical Properties of Pre-insulated Copper Foil::
Available on pads and spool.
Performance of Pre-insulated Copper Foil :
One side is copper, other side has insulating paper; In the middle is an imported pressure-sensitibe acrylic adhesive. Copper foil had strong adhesion and elongation. It is mainly due to copper foil’s excellent electrical properties that during processing it can have a good conductive effect. Secondly we use adhesive coated nickel to shield electromagnetic interference on the surface of copper foil.
Advantages of Pre-insulated Copper Foil:
1) Copper foil purity is higher than 99.95%
2) The function is to eliminate electromagnetic interference(EMI)
3) Electrostatic charge will be grounded, strongly bonded, good conductive propertied.
4) Reduces the necessary cross section of copper because of optimal shape in comparison to round wires
5) Ease of getting admittance for a winding construction due to the optimal safety
6) More reliable due to reduction of vibration, better thermal conductivity
7) Prevents danger of short circuit between primary and secondary windings
Characteristics of Pre-insulated Copper Foil:
1) Can be used below 100°C
2) Elongation is at about 5%, but can be changed in accordance with customer specifications.
3) Should be stored in a room temperature and can be stored for less than one year.
4) When in use, keep adhesive side clean of unwanted particles, and avoid repeated use.
