High-Voltage Reactor Dedicated Filament-Wound Insulation Cylinder

High-Voltage Reactor Dedicated Filament-Wound Insulation Cylinder

— 240mm Standard Model · Providing Structural Solutions for Reactor Core Insulation

1. Product Overview

This product is specifically designed for the winding support, interlayer insulation, and main insulation systems of high-voltage reactors (such as shunt reactors, series reactors, current-limiting reactors, etc.). It is a high-strength, high-precision insulation structural cylinder manufactured using continuous glass filament winding technology. The 240mm diameter is a standard model in this series, and custom production is available based on client drawings.

2. Core Technical Advantages

Feature Dimension Specific Performance and Process Description

1. Mechanical Structural Performance • Adjustable Axial/Radial Strength Ratio: Achieved by optimizing the winding angle (typically ±55° winding), balancing axial compressive strength and radial flexural strength to meet the electromagnetic force requirements during reactor operation. • High Dimensional Stability: Low coefficient of linear thermal expansion (≈1.5×10⁻⁶/°C), ensuring stable fit with metal components and windings under temperature variations, preventing thermal stress cracking. • High Load-Bearing Capacity: Can serve as the direct winding skeleton,承受ing winding tension and subsequent mechanical stresses from processing.

2. Electrical Insulation Performance • High Dielectric Strength: Power frequency withstand voltage can reach 35-50 kV/mm (depending on the resin system), with partial discharge levels controllable to ≤5 pC (per client standards). • Low Dielectric Constant and Loss: εᵣ ≈ 3.5-4.5, tanδ < 0.01 (@50Hz), reducing dielectric heating and improving equipment efficiency. • Excellent Tracking Resistance: Utilizes an arc-resistant resin formulation, meeting the CTI ≥ 600 V standard.

3. Environmental Resistance • Weather and Chemical Resistance: Resistant to transformer oil, SF₆ gas, acid/alkali vapors, etc., suitable for indoor, outdoor, and special environments. • Moisture and Permeation Resistance: Closed-cell structure with water absorption <0.1%, ensuring long-term operational insulation performance without degradation. • Flame Retardancy Rating: Options available for UL94 V-0 rating or IEC 60695 F1 class flame retardant standards.

4. Process and Precision • High Dimensional Accuracy: Inner/outer diameter tolerance controllable within ±0.2 mm, roundness ≤0.3 mm, meeting精密 assembly requirements. • Smooth Inner Wall/Grooved Design: Standard inner wall surface roughness Ra ≤1.6 μm; can provide integrated成型 structures such as pre-set block grooves, ventilation ducts, lead-out ports, reducing post-processing. • Surface Treatment: Options include anti-corona coating, semi-conductive layers, or sandblasting to suit different electric field grading needs.
