Product Detail

Description :

The KYN28 indoor metal-clad withdrawable switchgear(hereinafter short as switchgear) is a complete power distribution device for 3.6-24kV,3-phase AC 50Hz,single-bus and single-bus sectionalized system. It is mainly used for power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution and power system of factories, mines and enterprises, and starting of large high-voltage motor, etc,so as to control, protect and monitor the system. The switchgear meets IEC298,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker, it can also be used with VD4 from ABB,3AH3 from Siemens domestic ZN65A,and VB2 from GE, etc,it truly is a power distribution device with good performance.

FAQ
Q: What is the IP rating of UniGear ZS1?
A:
UniGear ZS1 has an IP4X rating per IEC 62271-200, protecting against solids ≥1mm (e.g., dust) in indoor environments. Liquid ingress protection isn’t rated; avoid direct water exposure.
Q: What is the heat dissipation of UniGear ZS1?
A:
UniGear ZS1's heat dissipation complies with IEC 62271, achieving ≤65K temperature rise at rated current via optimized airflow and conductive materials (e.g., galvanized steel). Ensures stable operation under full load.

What are the common overvoltages in the distribution network?
What are the common overvoltages in the distribution network?
Distribution networks, characterized by their wide distribution, large number of equipment, and low insulation level, are prone to insulation accidents caused by overvoltage. This not only reduces the stability of the entire distribution system and the insulation performance of the lines but also has a significant adverse impact on the safe operation of the power grid and the healthy and sustainable development of the power industry.From a circuit perspective, apart from the power source, the po

Analysis of Partial Discharge Principle (1)
Analysis of Partial Discharge Principle (1)Under the action of an electric field, in an insulation system, discharge occurs only in some regions and does not penetrate between the conductors with the applied voltage. This phenomenon is called partial discharge. If partial discharge occurs near a conductor surrounded by gas, it can also be called corona.Partial discharge can occur not only at the edge of a conductor but also on the surface or inside an insulator. The discharge occurring on the su

What are the differences between HVAC and HVDC?
What are the differences between HVAC and HVDC?
Difference Between HVAC and HVDCElectricity generated in power plants is transmitted over long distances to electrical substations, which then distribute it to consumers. The voltage used for long-distance power transmission is extremely high, and we will explore the reasons for this high voltage later. Additionally, the transmitted power can be in either alternating current (AC) or direct current (DC) form. Therefore, power can be transmitted using either HVAC (High Voltage Alternating Current)
