- Description
- Technical Specifications
-
SLVA low-voltage switchgear is a mid-to-high-end switchgear designed according to the standardization requirements of the power distribution network, featuring "safe and reliable, sturdy and durable, standardized and unified, universally interchangeable, reasonably graded, and widely used." Its model name comes from the uppercase initials of Standardized Low-Voltage Assemblies, abbreviated as SLVA low-voltage switchgear.
According to the busbar current, SLVA low-voltage switchgear is divided into three specifications: 1250A, 2000A, and 2500A, unifying the primary, secondary, and civil interface technical requirements to facilitate construction and operation & maintenance. In addition, the product reserves intelligent management interfaces. The cabinet design uses high-strength profiles, with structural improvements and reinforcements; different functional areas are reliably isolated, and heat dissipation structures are added to the cabinet door and top to ensure the switchgear's protection level and temperature rise meet technical requirements.
This product complies with standards GB/T7251.1, GB/T7251.8, GB/7251.12, GB/T20641, GB/T15576, and others.
