Bus duct combing: Understand "intensive bus duct"; the difference between flame retardant, fireproof and fire-resistant bus duct!
Classification of common Bus Ducts
1. Classification by process structure
1) Intensive bus duct The structure of the dense bus duct is generally "sandwich type". The conductor is mainly wrapped with insulating material, and several phases of conductive busbars are stacked without gaps. They can be completely tightly attached to the shell and insulated by the insulating material between the phases. Its characteristics are large current carrying capacity, faster heat dissipation, lighter and compact size to save space.
2) Air-type bus duct The structure of air-type bus duct is that there is a certain distance between the conductor phases and between the conductor and the shell, which can achieve air insulation and double insulation with insulating materials.
2. Classification by functional properties
1) Flame-retardant bus duct Usually used for equipment circuits for general non-fire equipment power supply, such as central air conditioning, general power distribution, etc., which can not burn under flame conditions.
2) Fire-resistant bus duct Refers to the fire power trunk line that can maintain the integrity of the circuit under flame conditions. It has both fire resistance and can meet the requirements of sprinkler. 3) Lighting bus duct Lighting bus duct is mainly used in some lighting systems and power places with small and medium loads but many branches such as high-rise buildings, hotels, shopping malls, offices, schools and hospitals. It has the characteristics of being very convenient to plug in and out electricity and beautiful.
Lighting busway is mainly used in some lighting systems and power-using places with small and medium loads but many branches, such as high-rise buildings, hotels, shopping malls, offices, schools and hospitals. It has the characteristics of convenient plugging and unplugging and beautiful appearance.
Compact busway
RenYun compact busway (Sandwich Busway) is a compact sandwich structure. The busway uses high-quality electrolytic copper with a purity greater than 99.95% as the conductor. After tinning, it is coated with high-quality insulating materials and has good flame retardant and insulating properties.
