선도적인 유연한 절연 버스바 제조업체

As a manufacturer of flexible insulated busbars, we specialized in innovative solutions for battery connections and power distribution systems. Our busbars are designed to offer superior electrical performance, high flexibility, and robust insulation to ensure safety and reliability in various applications.

Product structure of flexible insulated busbars

• Conductor layer: composed of flexible copper wire rows or tinned copper tape, providing high conductivity and flexibility.
• Wrapping layer: Polyester film or PTFE tape is used to wrap the conductor, enhancing insulation and anti-electromagnetic interference.
• Insulation Layer: The main insulating materials include polyvinyl chloride (PVC), cross-linked polyethylene (XLPE) or silicone rubber, with a thickness of 1.8-2.1mm, providing electrical isolation.
• Armor Layer: Interlocking metal armor (e.g., stainless steel tape) provides mechanical protection against external damage.
• Sheath layer: The outer layer is made of flame retardant and corrosion resistant material (such as halogen free PVC), with protection level up to IP68.

Production process of flexible insulated busbars

1. Conductor processing

• Copper/aluminum is drawn into fine wires by wire drawing machine and annealed to enhance flexibility.
• The stranding process weaves multiple strands of conductors into flexible copper wire rows to enhance current-carrying capacity.

2. Insulation treatment

• Wrapping layer: polyester film or mica tape is wrapped by automatic wrapping machine to reduce partial discharge.
• Extrusion molding: PVC or XLPE evenly cover the conductor through high temperature extruder, thickness error ≤ 0.1mm.

3. Armor and sheath

• The metal armor layer wraps the insulating layer through interlocking technology to enhance the compressive strength (can withstand 50kA short-circuit current).
• The outer sheath adopts co-extrusion technology to ensure weather resistance and flame retardancy.

4. Testing and Packaging

• Voltage withstand test: 3.5kV frequency withstand voltage for 1 minute without breakdown.
• Intelligent detection: integrated current/temperature sensor, support real-time online monitoring.

절연 버스바란 무엇입니까?

Insulated busbar is a power transmission and distribution equipment that realizes electrical isolation by wrapping insulating material outside the conductor, which is different from the bare rigid busbar. Its classification includes:

• Flexible insulated busbar: adopting multi-layer flexible conductor and insulation structure, suitable for dynamic or complex environment.
• Tubular insulated busbar: copper tube as conductor, covered with PTFE insulation, used in high-voltage scenarios (e.g. substations).
• Enclosed busway: metal shell embedded insulated busbar, mostly used in building power distribution.

주요 기능 및 이점

1. Energy efficient: Large surface area of the conductor, low skin effect, reducing line loss by more than 30%.
2. Safe and reliable: 3.5kV voltage without breakdown, insulation resistance ≥ 15000MΩ, support for outdoor wet environment.
3. Convenient installation: Flexible structure without customized elbow, installation efficiency increased by 60%.
4. Cost optimization: No intermediate joints, construction costs reduced by 50%, maintenance-free for life.

버스바를 절연하는 방법은?

버스바를 절연하는 것은 전기 단락을 방지하고 환경 요인으로부터 보호하며 안전한 취급을 보장하기 위해 전도성 재료 주위에 보호 층을 적용하는 것을 포함합니다. 다음은 버스바를 절연하는 일반적인 방법입니다.

1. Material selection

• High temperature scenario: PTFE (temperature resistance 340℃) or silicone rubber (temperature resistance 200℃).
• Environmental scenario: halogen-free flame retardant materials (oxygen index ≥ 30%).

2. Technology

• Multi-layer winding: alternately winding semi-conductive tape and insulating tape to eliminate electric field concentration.
• Vacuum impregnation: filling epoxy resin for tubular busbars to enhance insulation strength.
• Co-extrusion molding: synchronous extrusion of conductor shielding layer and main insulation layer to reduce interface defects.

3. Liquid Insulation

액상 절연 화합물을 버스바에 도포하여 원활하고 유연한 절연층을 만들 수 있습니다.

단계:

• 버스바 청소: 버스바 표면이 깨끗한지 확인하세요.
• 액상 단열재 적용: 버스바를 액상 단열재에 솔질하거나 뿌리거나 담그세요.
• 건조 및 경화: 제조업체의 지침에 따라 화합물을 건조하고 경화시킵니다.
