Product Number:ABB UniGear ZS1 Portfolio

Product Overview

UniGear ZS1 is a medium-voltage air-insulated switchgear of ABB Company, which is widely used in the field of power distribution and control. The following is its related introduction:

Product Overview:

Voltage level: Mainly used for primary distribution, with a rated voltage up to 24kV.

Current and short-circuit withstand capacity: The rated current can reach up to 4000A, and the maximum short-circuit withstand current can reach up to 63kA. It can withstand a certain period of short-circuit current impact, ensuring the safety of the system in case of a fault.

Application scenarios: It is suitable for a variety of complex and high-demand places, such as offshore platforms, container ships or cruise ships, mines, as well as public substations, power plants, chemical plants, etc.

Product Features:

Advanced design: It adopts a uniform electric field and composite insulation design, with a compact structure that can reduce the user's civil construction investment. It has various types of cabinets such as single busbar cabinets, double busbar cabinets (including double busbar and double circuit breaker forms, etc.) and double-layer cabinets. These cabinet types can be spliced with each other without the need for transfer cabinets, and the configuration is flexible.

Safe and reliable: It provides a complete mechanical safety interlock to prevent misoperation. It has passed all the type tests stipulated by the International Electrotechnical Commission standards and Chinese national standards, such as internal arc combustion tests, etc., which can effectively protect the safety of operators and equipment. The high-voltage cabinet body is made of imported aluminized zinc plate with high strength, anti-corrosion and no need for spraying. The main busbar adopts the "D" type structure imported from Finland, which has good dynamic and thermal stability characteristics. The branch busbar adopts imported copper busbar with R5 rounded corners, which can avoid tip discharge.

Outstanding performance: As a key medium-voltage switchgear product of ABB, it boasts outstanding performance and rich operational experience. Its circuit breaker product series has accumulated over one million units of safe operation experience.

High degree of intelligence: It can be equipped with electrically operated circuit breaker trolleys and grounding switches to achieve intelligent operation in substations. It can also be combined with intelligent solutions to monitor the temperature rise and mechanical characteristics of switch cabinets and predict the health status of the equipment. It is also possible to configure a digital solution for medium-voltage switches, adopting electronic transformers and IEC 61850 digital communication technology to achieve the sharing of sampling signals and the standardization of switchgear.
