deskribapen laburra:
Our 33kV Outdoor Medium Voltage Vacuum Circuit Breaker (VCB) is a high-end switching and protection device engineered for 33kV, 50Hz three-phase AC outdoor power systems. Adopting advanced vacuum arc-extinguishing technology, it features zero gas leakage, no environmental pollution, and ultra-fast arc extinction. The product is equipped with a high-strength spring operating mechanism, ensuring stable action and high mechanical reliability. Its insulation system uses hydrophobic silicone rubber bushings, providing excellent resistance to pollution, gatz spray, and ultraviolet radiation. IEC-a betetzen duena 62271-100 eta GB 1984 estandarrak, this VCB is designed for harsh outdoor conditions, including high altitudes (≤4000m) and heavy pollution areas. It is widely used in 33kV substations, power transmission lines, industrial parks, and renewable energy projects, providing a safe and reliable solution for grid protection and control.
1. Produktuen ikuspegi orokorra Produktuen ikuspegi orokorra
The 33kV Outdoor Medium Voltage Vacuum Circuit Breaker is a key component in the 33kV power distribution network, primarily used to close, carry, and break normal load current, as well as to quickly isolate short-circuit and overload faults. It integrates a vacuum interrupter, operating mechanism, insulation bushings, and a stainless steel enclosure into a compact, weatherproof unit. The fully sealed design prevents the ingress of moisture, hautsa, and corrosive gases, ensuring long-term stable operation. The product supports manual, electric, and remote control operation (aukerakoa), making it suitable for both conventional and smart grid applications. With its high insulation level and robust structural design, it effectively meets the operational requirements of 33kV outdoor power systems in various climates and environments.
