72.5kV OIP Wall Bushing for Substations

Overview

As a crucial high - voltage insulation component in power systems, 72.5kV OIP (Oil - Impregnated Paper) Wall Bushing is mainly applied in transformers and switchgear. Compared with Epoxy Resin Bushing, it boasts a higher voltage rating. Common voltage classes for OIP Bushings span 72.5kV, 145kV, 252kV, 363kV, 420kV, and 550kV. The outer insulation can be porcelain or silicone rubber, customizable to meet diverse demands.

Advantages Over Competitors

Insulation Performance

While some competing products use different insulation materials, OIP offers excellent dielectric strength, making it highly suitable for ultra - high voltages. This outperforms many alternatives in maintaining stable insulation under high - voltage operation.

Thermal Stability

Can operate at a long - term temperature of up to 105°C and has strong short - term overload capability. In contrast, certain competitors may have lower temperature tolerance or less robust overload performance, which could limit their application in harsh operating conditions.

Mechanical Strength

Features a high mechanical failing load. Compared to rival products, it provides more reliable support for conductive parts passing through walls in power stations and substations, reducing the risk of mechanical failure during installation and operation.

Service Life

With a design lifespan exceeding 30 years (extendable with proper maintenance), it outlasts some competitors. This long service life means lower replacement frequency and overall lifecycle costs for users.

Environmental Adaptability

Suitable for both indoor and outdoor use. Unlike some competing bushings that may be limited in their environmental application scope, this OIP wall bushing can withstand harsh climates, including heat, humidity, and corrosive environments, ensuring consistent performance across diverse settings.

Manufacturing and Customization

Utilizes a mature manufacturing process with high - temperature firing and strict control measures, resulting in smooth surfaces and standardized shapes. Also, available in various models and sizes (e.g., 1kv/630A, 10NF250, XP70 specifications can be referenced for customization ideas), allowing better adaptation to specific industrial needs compared to less flexible competitors.
