Comparison Of Advantages Between High Temperature Resistant Neutral Blocks And Conventional Neutral Blocks
Material and heat resistance
High temperature resistant neutral blocks: They are usually made of special materials such as high-purity copper, high-temperature plastics, or ceramics, which can maintain strength and stability in high temperature environments. For example, copper wire terminals are made of high-purity copper material, which has good thermal conductivity with a thermal conductivity of about 401W/(m · K) and a high melting point of about 1083 ℃, effectively maintaining performance at high temperatures. In addition, there are neutral blocks produced using glass fiber flame-retardant PBT material, which have excellent heat resistance and mechanical strength, high thermal deformation temperature, and can withstand current loads at high temperatures.
Conventional neutral blocks: They are usually made of general plastic materials, which may soften, deform, or even melt in high temperature environments, leading to unstable connections or faults such as wire short circuits.
Structure Design
High temperature resistant neutral blocks: usually have a large cross-sectional area and a simple, compact structure, which is conducive to heat conduction to the surrounding environment and reduces the accumulation of heat at the connection. At the same time, its design also considers the thermal cycling problem in high-temperature environments, which can maintain the stability of the connection during multiple temperature increases and decreases.
Conventional neutral blocks: Due to their complex structure or small cross-sectional area, they may have poor heat dissipation at high temperatures, leading to heat accumulation and performance degradation.
Electrical performance and safety
High temperature resistant neutral blocks: They can maintain good conductivity in high temperature environments, ensuring stable power transmission. At the same time, they also have low resistance and stable connections, which can reduce the loss of electrical energy converted into thermal energy, further reducing heating problems caused by poor connections. In addition, some high-temperature resistant neutral blocks also have flame retardant properties, which can effectively prevent safety issues such as fires from occurring.
Conventional neutral blocks: In high-temperature environments, material softening or deformation may cause a decrease in electrical performance, and even pose safety hazards.
