CY-L Copper Dense Busway System

High-quality conductor and excellent insulation materials High performance,High strength and IP65+protection level

Improved safety performance

The CY-L series busway utilizes high-quality conductors and insulating materials with an optimized structural design providing low line losses to significantly enhance transmis- sion efficiency and reduce costs; The busway's superior heat dissipation performance and stable temperature rise levels ensure long-term operational stability;
Excellent insulation performance

Utilizes DuPont polyester film as the primary insulatior material, rated for Class B (130°C) thermal endurance; Terminal sections reinforced with Class F (155°C) black epoxy resin for superior mechanical fixaition and insulation reinforcement； Flame-retardlant performance meets UL94 standards, ensuring halogen-free and eco-friendly insulation properties;
Enhanced protectioncapability

The grounding system employs an advanced integrated grounding method (IGB structure)with 50%phase line capacity,ensuring ground line integrity and continuity; During high-capacity ground faults,the effective grounding mechanism safeguards the entire system while minimizing eddy current losses; The busway housing adopts Dacromet rivets assembled with minimal spacing,delivering superior short-time withstand performance,enhanced safety,and eliminating electric shock risks;

"Sandwich"/"亚”structure

The compact conductor arrangement with integrated heat dissipation results in lower temperature rise of the busway; The tightly structured busway occupies less building space;
Active connector

Allows quick disassembly during maintenance and creates electrical isolation for safe servicing; Incorporates precision alignment features to enhance installation efficiency and ensure assembly accuracy; Utilizes silver/tin-plated contact surfaces with double-sided overlapping joints to expand effective conductor cross-sec- tion,guaranteeing ow-resistance electrical performance;
Higher transmission efficiency and lower

The CY-L series housing adopts a fully enclosed structure formed by integrated molding technology,reducing dust accumulation inside the busway and applying electrostatic spray polyester powder; It addresses the weak protection issue at joints of full-aluminum-profile housing busways,achieving an IP66 protection rating for the entire busway with excellent corrosion resistance.
