Fabricant leader de barres omnibus en cuivre isolées par tubes thermorétractables

En tant que fabricant leader de jeux de barres en cuivre isolés par des tubes thermorétractables, nous sommes spécialisés dans la production de solutions fiables et de haute qualité pour une distribution d'énergie efficace et une isolation électrique. Nos jeux de barres sont conçus pour répondre aux exigences rigoureuses des systèmes électriques modernes, offrant une conductivité supérieure, une isolation robuste et une durabilité accrue.

Production process:

1. Raw material processing: Screening copper rows and insulating materials, cutting and cleaning the surface (removing oil, burrs).

2. Composite process:

• By irradiation cross-linking or chemical cross-linking technology, the polyolefin material is laminated with the copper rows to control the uniformity of the layer thickness.
• Curing treatment to enhance the bonding strength.

3. Heat shrink molding: Heating to 120℃~140℃, using oven or hot air gun for uniform shrinkage, to avoid air bubbles or localized overheating.

4. Post-treatment and inspection: After cooling, remove the excess sleeve, check the surface flatness, insulation properties (such as voltage resistance test).

Product advantages:

• Excellent electrical performance:  High dielectric strength (≥25kV/mm), reduce the risk of interphase flashover, temperature rise is 15~20K lower than bare copper, can reduce the choice of copper specifications.
• Mechanical and weather resistance: Tensile strength ≥8MPa, elongation at break ≥300%, chemical resistance and UV aging.
• Convenient installation: Support stove, heat gun and other heating methods, adapt to mass production and on-site construction.
• Environmental safety: Halogen-free flame retardant materials to reduce fire toxicity, in line with international environmental standards.
• Economy: Reduce the volume of equipment, extend the life of busbar, reduce maintenance costs.

Applications :

1. Power system:

• Insulation protection of 10kV~35kV substations, distribution cabinets, bus ducts.
• Insulation enhancement of ultra-high voltage transmission lines (e.g. State Grid project).

2. new energy facilities: Wind farms, photovoltaic power station converging busbar and inverter connection.

3. rail transportation: Insulation of busbar of power supply system of subway and high-speed railway.

4. industrial equipment: Busbar protection of large motors, UPS power supply, high and low voltage switchgear.

5. construction field: The safety insulation of the power system of ultra-high-rise buildings.
