Product description

Product Introduction

Brazil‑Standard 15‑36.2kV 160A Composite Insulation High‑Voltage Bushing is designed for Brazilian power grid operating conditions, with rated voltage 15‑36.2kV and rated current 160A, complying with relevant INMETRO technical requirements. It is widely applied on high‑voltage equipment such as transformers and switchgears, enabling high‑voltage conductors to pass through equipment enclosures, performing functions of current‑carrying, electrical insulation and mechanical support. Adopting composite insulation structure, it features superior hydrophobicity, anti‑pollution flashover performance, light weight and high shock resistance compared with conventional porcelain bushings. Suitable for indoor‑outdoor dual‑use distribution under humid and heavily‑polluted service conditions in Brazil.

Component Composition

Central Conductive Rod (Current‑carrying Conductor): Core current-carrying part, bears 160A rated current for power conduction.
FRP Fiberglass‑Reinforced Epoxy Insulation Core Tube: Main insulation structure, provides insulation protection and mechanical strength.
Silicone Rubber Shed Housing: Increases creepage distance, resists weathering and pollution flashover for outdoor use.
Mounting Flange Fitting: Fixes and positions the bushing, seals and isolates internal and external environments.
Top & Bottom Termination Fittings: Connects high-voltage lines, ensures stable 160A current conduction.
Sealing Assemblies: Seals gaps, prevents dust and moisture from entering equipment.

Technical Parameter

  • Rated Voltage: 15～36.2kV, compliant with Brazilian medium voltage grid standards
  • Rated Current: 160A, suitable for long-term rated current operation of distribution systems
  • Power Frequency Withstand Voltage: 95kV (1min), no breakdown and no flashover
  • Lightning Impulse Withstand Voltage: 170kV, resisting high-voltage transient impact
  • Operating Temperature: -40℃～+85℃, adaptable to all regional climates in Brazil

Specification Description

Brazil‑Standard 15‑36.2kV 160A Composite Insulation High‑Voltage Bushing comes with multiple specifications and dimensions. It can adapt to various flange sizes, mounting lengths, creepage requirements and different on‑site project conditions for proper equipment matching. Should you have demands for special sizes, interfaces or other customizations, please provide relevant technical information and feel free to contact us for consultation.
