NPS01-F40 -1500 AC 3+MP Surge Protective Device

Product Overview

To address severe electrical stresses found across modern wind generation collector lines, our engineers developed the NPS01-F40 -1500 AC 3+MP Surge Protective Device as a dedicated high-voltage transient shield. Utilizing a 3+MP configuration combining high-purity zinc oxide varistors with an isolated spark gap, this NPS01-F40 -1500 AC 3+MP Surge Protective Device prevents phase-to-ground leakage while suppressing destructive 40kA overvoltage surges. We manufacture this protective device to safeguard multi-megawatt wind turbine step-up transformer circuits, medium-voltage collection boxes, and offshore wind platform distribution lines.

Application Scenarios

Wind Turbine Step-Up Systems: Low-voltage side of turbine step-up transformers operating at elevated AC voltages.
Offshore Wind Platforms: Substation auxiliary switchgear and inter-array cable monitoring panels.
Utility Wind Collector Substations: Main collector feeder cubicles and power quality filtering cabinets.

Product Advantages

FAQ

Q1: Why is the 3+MP topology preferred in offshore wind auxiliary circuits?

A1: The spark gap blocks normal ground leakage, preventing corrosion of grounding bonds and avoiding false trips on sensitive offshore residual current monitors.

Q2: What payment methods are accepted for overseas purchase orders?

A2: We accept standard T/T payments (50% deposit upon order confirmation, 50% balance before factory dispatch) in USD, EUR, and RMB.
