Enameled Wire Spring

Solution

Product Description

Enameled Wire Spring is a precision-engineered component crafted from high-quality enameled copper wire or enameled aluminum wire. Designed for electrical, mechanical, and thermal applications, this spring combines elasticity with excellent insulation. Through advanced enameled wire manufacturing, the coated conductor ensures superior durability, stable resistance, and efficient conductivity. It is ideal for dynamic components in motors, sensors, relays, and intelligent electronics.

Key Features

 High Electrical Insulation Performance

The Enameled Wire Spring is coated with polyester, polyurethane, or polyamide-imide enamel, providing excellent dielectric protection.

• Insulation Class: 130°C / 155°C / 180°C (Class F/H)

• Dielectric Strength: ≥1500V

• Insulation Resistance: ≥10⁸ Ω
  This ensures safe operation by preventing short circuits, making it suitable for motors and precision sensors.

 Precise Resistance Control

Manufactured through advanced enameled wire manufacturing, the spring maintains consistent resistance and coil spacing.

• Resistance Tolerance: ±5% / ±2% (customizable)

• Conductor Resistivity: 0.01724 Ω·mm²/m (Copper)
  Ideal for relays and signal devices where accurate electrical response is essential.

Excellent Mechanical Elasticity

The spring is wound under constant tension to ensure strong elasticity and fatigue resistance.

• Spring Force: 0.05N – 5N (customizable)

• Fatigue Life: ≥500,000 compression cycles
  Even under repeated loading, it maintains its shape and rebound strength.

Heat & Chemical Resistance

The enamel coating offers superior heat and chemical durability.

• Operating Temperature: -60°C to +200°C

• Chemical Resistance: Oil, alcohol, insulating varnish, cooling liquids
  This makes it ideal for industrial-grade motors, electromagnetic applications, and high-temperature environments.
