1. Solid Connection
Precise interface and solid structure ensure tight and stable fuse connection, prevent loose virtual connection, such as photovoltaic system can avoid arc caused by vibration, ensure safety.
2. High Insulation
High quality insulation material, in wet and dry environment can effectively prevent leakage, to ensure the safety of equipment and personnel.
3. Meet the Standard
Follow international and domestic standards (such as IEC standards), each link is strictly controlled, suitable for all kinds of photovoltaic systems.
4. High Adaptability
Suitable for various fuse specifications, the fuse can be flexibly replaced when the current demand of the photovoltaic system changes (expansion or load adjustment).
5. Low Contact Resistance
The special contact structure makes the contact resistance low, reduces the power loss, and can improve the power generation efficiency in large-scale power stations.
6. High Heat Dissipation Performance
The material and structure are conducive to heat dissipation, which can quickly dissipate heat in case of overload or short circuit, ensuring normal operation and extending life.
Q1: Are you a trading company or a manufacturer?
A: We are Integration of industry and trade, our company has a history of 40 years. We have been specializing in the production of a series of photovoltaic electrical products, such as circuit breaker, pv combiner boxes, pv connector, surge protector, pv fuses, pv tool accessories and etc.
Q2: If OEM is acceptable?
A: We can provide OEM and ODM services. We have many different specifications and appearances for customers to choose.
Q3: Do you provide sample? Free or charge?
A: We can provide free samples to customers, but only one piece, but customers need to bear the freight. For some special products, we also offer free samples. Considering their particularity, we usually refund the sample fees to customers after they place formal orders.
Q4: How long is your delivery time?
A: Our delivery time is determined according to the purchase quantity. Generally, it is about 3-40 days, less than 300 pieces within 5 days, 300-2000 pieces within 7-15 days, 2000-20000 only within 15-40 days.What are the requirements for the installation environment when installing a fuse base?
Q5: How do I ensure a strong connection to other devices?
A: First of all, use the appropriate installation tools, such as screwdrivers, wrenches, etc. according to the installation manual. When attaching bolts, ensure that they are tightened to the specified torque value.
Q6: Determining factors of rated voltage and relation with actual voltage?
A: According to insulation withstand voltage, electrical clearance and creepage distance determined. The actual voltage must be less than or equal to the rated voltage, otherwise the insulation breakdown may be lost.
Q7: Is the fuse break time fixed and influencing factors?
A: The fusing time is not fixed. It is mainly affected by the size of the current (the larger the current, the shorter the fuse time), and the ambient temperature also has a certain impact (the fuse time may be shortened at high temperature, and it may be extended at low temperature, but the impact is small).
Q8: How to ensure overload fusing and normal fusing?
A: Through precise material formulation and process, material and size selection according to rated current, normal current heat dissipation is normal, overload heat dissipation capacity is fused.
Q9: Can you use other brands of fuses instead?
A: It is not recommended to use other brands of fuses instead. Different brands have differences in materials, processes, fusing characteristics, etc., which may lead to inaccurate fusing, no protection or safety hazards.
Q10: Precautions for replacing fuses with different rated current?
A: Make sure that the rated current matches the circuit requirements, cut off the power supply before replacement, and use a suitable tool (such as tweezers) to remove the old and install the new, taking care to avoid damage to the fuse and ensure good contact.
