Product Details

The BTB-NH series is a volcanic rock mineral full casting bus duct, which has the advantages of ultra-high protection grade (protection grade up to IP68), waterproof, fire prevention, corrosion prevention, explosion-proof, safety and environmental protection, and lifelong maintenance-free. The products have passed 3C, CQC, KEMA and other certifications, meet the requirements of IEC60439, GB7251 and other standards, adopt a fully closed casting method, and have the characteristics of good dynamic thermal stability, low impedance and low loss, service life of more than sixty years. As the main product of Beitoba (Guangdong) Electric Power Technology Co., Ltd., BTB-NH series volcanic rock mineral full pouring busbar can be used in all kinds of power transmission and distribution systems that require high protection and harsh environment. It has been widely used in modern petrochemical, coal mine, electronic workshop, dock, shipbuilding, sewage treatment, iron and steel industry and other fields.

Product advantages:
1 The protection level reaches IP68, which can be soaked in water for a long time to provide stable power transmission
2 Stable performance, high dynamic thermal stability, extremely low fire load
3 Compact product design, small space requirements, easy product installation and maintenance-free, short debugging time
4 volcanic silica mineral insulation material, is not spontaneous combustion, non-combustion, self-extinguishing, and will not emit any toxic gases of excellent insulation materials

Product features:
1. Processing technology: the introduction of German vacuum casting mixing equipment, digital operation can be continuous measurement of raw materials, uniform mixing, and stirring in a vacuum state
2. Production formula: After the volcanic silica mineral insulating material and curing agent are evenly mixed, the shrinkage is small, the fluidity is strong, the curing is convenient, the adhesion is strong and the solidification time is short
3. Busbar connection: the form of on-site pouring connector is adopted, the connection is simple and time-saving and firm
4. Waterproof design: IP68 protection level can prevent the entry of dust, and can be in the case of continuous immersion can also be long-term reliable operation
5. Fire protection design: BTB-NH series bus duct can be achieved without making a special bus fire prevention unit to prevent the spread of flame under flame conditions
6. Anti-corrosion design: The cured synthetic material has excellent alkali resistance, acid resistance and solubility, resistance to most molds, and can be used under harsh conditions
7. Explosion-proof design: the whole section is completely enclosed. The explosion-proof grade of our full pouring bus can reach EEx m II T5 (D2G5), so it can be applied to explosion-proof places. If the explosion-proof grade exceeds EEx m II T5 (D2G5), please contact our company to provide a proper scheme to meet the explosion-proof requirements under different conditions.
