High Temperature Resistantance PE2+PA Submersible Pump Winding Wire

Dimension Specifications

• Conductor material: 99.97%+ high-purity oxygen-free copper wire
• Conductor diameter range: Φ0.20 mm to Φ5.00 mm
• Conductor structure options: Single-strand, 7-strand, 19-strand, 37-strand, 49-strand and 61-strand stranded configurations, which can be customized according to different motor power and stator slot design requirements
• Insulation & sheath total thickness: 0.25mm to 1.8mm, with precise extrusion tolerance control to maximize the motor stator slot fill rate and effectively improve the power density of submersible motors

Electrical & Voltage Withstand Performance

• Rated operating voltage: 450/750V, covering low-voltage 380V to medium-high voltage 10kV submersible motor application scenarios
• Power frequency water immersion withstand voltage: No breakdown after 1-minute test at 1760V; reinforced models can pass 3000V/min high-strength withstand test
• Inter-turn impulse withstand voltage: Fully meets the strict requirements of submersible motor frequent start-stop scenarios, effectively avoiding insulation damage caused by instantaneous voltage surges
• 20℃ volume resistivity: ≥1×10¹² Ω·cm, with extremely low medium loss, ensuring stable electrical performance during years of continuous underwater operation

High Temperature & Environmental Adaptability

• Maximum continuous allowable operating temperature: 150℃, specially adapted for high-temperature hot water submersible pumps and geothermal energy extraction equipment
• Applicable water temperature range: +5℃ to +105℃, special customized models can withstand instantaneous high temperature impact up to 280℃
• Water quality corrosion resistance: Adapt to groundwater with pH 6.5-8.5, chloride ion resistance up to 400mg/L, and can operate stably for a long time in mine drainage, agricultural irrigation and urban water supply scenarios
