2. Introduction
There are different kinds of enameled wire. Let
Zhengzhou LP Industry Co., Ltd introduce for you.

3. Acetal enameled wire
Temp Class:There are two heat
level of 105 and 120.
Advantages: It has good
mechanical strength, adhesion
resistance, transformer oil and
refrigerant resistance
performance.
Disadvantages: Poor moisture
performance, low heat softening
temperature resistance, weak
durable benzene - alcohol
performance such as a mixed
solvent.
Application: It is now only used in
a small amount for oil-immersed
transformers, oil-filled motor
windings.

4. Polyester and modified polyester enameled wire
Temp Class: Ordinary polyester enameled
wire, thermal level is 130. And the
modified enameled heat level is 155.
Advantages: The product has high
mechanical strength and good elasticity,
scratch, adhesion, electrical properties
and solvent resistance, which is China's
current production capacity of the largest
species, accounting for about two-thirds.
Disadvantages: The weakness of product is
poor thermal shock resistance, low
moisture resistance properties.
Application: It is widely used in various
motors, electrical, instrumentation,
telecommunications equipment and
home appliances.

5. Polyurethane enameled wire
Temp Class: Heat level rates
130,155,180,200.
Advantages：The biggest feature is a
linear welding resistance, high
frequency performance. And it is
easy to be colored. It also has good
moisture resistance performance.
Disadvantages：The weakness is
low heat resistance, bad production
flexibility and poor adhesion of
large-size line, so the product's
specification is always medium or
fine wire.
Application: It is widely used in
electronic appliances and precision
instruments, telecommunications
and instrumentation.

6. Polyester-imide / polyamide enameled wire
Temp Class: Thermal level is 180.
Advantages: The product has high
shock resistance, high
temperature softening breakdown,
good mechanical strength,
solvent resistance and refrigerant
properties.
Disadvantages: The weakness is
easy to hydrolysis in the closed
condition.
Application: It is widely used for
high heat-resistant electrical,
electronics, instrumentation,
power tools and other power dry-
pressed winding.

7. Polyester-imide / polyamide-imide enameled wire
Temp Class: The heat level is 200.
Advantages: It is currently more
widely used in the world. The
product has high heat resistance,
anti-freezing agent, resistant to
cold, excellent radiation-resistant
properties, high mechanical
strength, electrical performance
and stability, good chemical
resistance, resistance to freezing
agent performance and strong
overload capability.
Application: It widely used in the
next refrigerator compressors, air
conditioning compressors, power
tools, explosion-proof motors and
heat, cold, radiation-resistant,
overload conditions such as use of
electrical, electronics.
