MSS H & MSS L Intelligent Insulated Switchgear - Complete Product Introduction

1. Product Brief Introduction

The MSS H and MSS L Intelligent Insulated Switchgear are an integrated metal enclosed switchgear jointly developed by our technical experts and European switch technology experts based on the concept of product lifecycle and the Internet of Things. It complies with IEC and GB/DL standards and features a comprehensive range of cabinet configurations, with characteristics of full insulation, full shielding, full sealing, low temperature rise and maintenance-free operation. The EIS Power Distribution Internet of Things System enables real-time monitoring of the equipment's operating status. Its modular design helps customers control costs in terms of operation and maintenance, overhaul, fault handling and scrapping, supporting industrial customers to create higher production value.

2. Main Applications

• MSS H Intelligent Insulated Switchgear: Suitable for large power load units such as power grids, power plants, petroleum and petrochemical industries, metallurgy, coal chemical industry, as well as places with harsh environments, and can also be used in municipal administration, ports and terminals and other places.
• MSS L Intelligent Insulated Switchgear: Applicable to industries such as urban and rural power grids, industry, municipal administration, commercial buildings, aerospace, ports and terminals, rail transit, as well as places with harsh environments.
• Special application scenarios for MSS H & MSS L in harsh environments: High humidity areas, high altitude areas, high temperature areas, dusty areas, corrosive gas areas.

3. Operating Environmental Conditions

  Note: In case of special operating conditions, please contact the equipment manufacturer.
  

4. MSS H Product Characteristics

• The primary conductive parts adopt full solid insulation, which is unaffected by the surrounding environment and resistant to various harsh conditions. All insulation surfaces are shielded and earthed to eliminate the occurrence of phase-to-phase short-circuit faults.
• Visible isolation fracture and earthing position enable operation and maintenance under safe conditions. Tubular copper busbars are adopted to ensure uniform electric field distribution, which effectively reduces the probability of tip discharge and results in low partial discharge of the entire cabinet.
• The primary main circuit realizes true maintenance-free operation.
• No risk of gas leakage throughout the equipment service life.
• Compact in size and light in weight, which effectively saves building area and civil construction costs.
