KEY-148 Natural Refined Insulating Oil

KEY-148 Natural Refined Insulating Oil

Product Highlights

High flash point	Maintain long-term stability	High insulation
Good insulation	Good lubricity	Good biodegradability

Product Introduction

Ultimate Thermal Safety and Ecological Compatibility: With a flash point exceeding 180°C, KEY-148 delivers exceptional fire and explosion resistance for equipment. Simultaneously, its near-perfect biodegradability ensures zero damage to soil and aquatic ecosystems in extreme leakage scenarios, making it a truly "eco-friendly" insulating oil.
Optimized Dielectric Synergy: Featuring a high dielectric constant of 2.0-3.2, it achieves excellent compatibility with insulating paper (approximately 4.4). This synergy effectively balances the internal electric field distribution within the insulation system, significantly reducing the aging rate of insulating paper and fundamentally extending the transformer's entire lifecycle.
Unique Gas Adsorption and Self-Purification Mechanism: Possesses a natural "breathing" function with exceptional solubility for oxygen and moisture. This characteristic not only inhibits the hydrolysis aging of insulating paper but also effectively suppresses partial discharge by absorbing internal gases, maintaining long-term stability within the equipment environment.
Sustainability throughout the entire lifecycle: Derived from renewable plant resources, it fully aligns with global carbon neutrality and green energy transition strategies, providing enterprises with an ideal solution to fulfill environmental responsibilities from the source.
