The 38kV High Voltage Electrical Distribution Standard Fuse Cutout is designed to provide reliable overcurrent and short-circuit protection for overhead power distribution systems. This 38kV high voltage fuse cutout is widely installed on utility poles to protect transformers, distribution lines, and electrical equipment from fault conditions.
Manufactured to meet utility-grade standards, the 38kV electrical distribution fuse cutout features stable insulation performance, dependable arc-extinguishing capability, and clear drop-out indication after fuse operation. It is an essential high voltage standard fuse cutout 38kV for safe and efficient power system protection.
Reliable overcurrent and short-circuit protection
Clear drop-out indication for easy fault identification
Stable insulation performance for high voltage operation
Effective arc extinguishing for safe interruption
Designed for outdoor distribution environments
Utility-grade structure for long service life
Compatible with standard high voltage fuse links
Reduces damage to transformers and distribution equipment
High performance of weather aging resistance
For porelain insulator, the porcelain body connects with hardware fitting by cement
pouring, we use the (por-rok)ANCHORING cement manufactured by CGM INC from
USA. This kind of cement has rapid solidification, high mechanical strength, low
expansion coefficient and superior weather resistance.
For polymer insulator, the hardware fitting crimped onto fiberglass rod, material of housing and sheds manufacture of high-temperature Vulcanized Silicone Rubber, and the insulator moulded by one piece injection molding. It has good sealing performance and good performance of tracking and erosion resistance.
All ferrous parts processed by hot dip galvanized, its zinc coating more than 86u, it has good corrosion resistance.
