High tension wire is special self-bonding alloy wire designed for voice coils and designated as DHT, SDHT, UDHT as described below. The wire has tensile strength 25% higher than copper wire, more durable, higher conductivity and with better anti-bending performance.
Features:
◆ The tensile strength is 20%-90% higher than copper wire(suitable for high winding process, prevent breakage of wire at pin connection).
◆ Conductivity > 77%
◆ The properties of insulation and self-bonding layer is the same as enamelled copper wire.
◆ Good solderability, the same as enamelled copper wire.
Parameters of high tension wire:
Elongation vs Tension:
Product range: Φ 0.020-0.15mm (AWG52-34)
High Tension Wire Designation:
① Product code:
DHT= Durable high tension wire
SDHT= Supper durable high tension wire
UDHT= Ultra durable high tension wire
② Insulation thickness:
③ Type of self-bonding layer
④ Type of insulation
⑤ Thermal class(B=130,F=155,H=180)
⑥ Diameter of conductor
Applications:
The wire is widely used in high class voice coil(micro speaker), vibration motor, Mic coil, magnetic head
coil, mobile phone coil, moving coil or other Special-shaped coil.
