LDZKW Series Split-core Type Outdoor Waterproof Current Transformer
Product Description
Product Overview
The series of current transformers use high quality imported silicon steel sheet with high permeability as magnetic conductivity material, which has the characteristics of divisible iron core and small magnetic circuit loss. The half-ring type iron core and secondary winding are vacuum poured into the flame retardant plastic shell with high quality epoxy resin, which is moisture-proof and stable in performance without maintenance.During installation, clamp the two semi-circles on the split-phase cable, and use the clamps to hold it tightly with the cable, which is harmonious and beautiful. It is applied to outdoor overhead lines, and is equipped with a customized silicone protective cover, which has the functions of anti-ultraviolet, anti-aging, and anti-moisture. Make sure that the transformer body does not cause water entry along the cutting surface of the iron core and cracking of the transformer surface due to the influence of the outdoor environment.
Product Features
* Split-core structure, easy to install on site and easy to operate. Quick and easy installation or removal without disconnecting the primary cable under test.
* Instrument security factor ≤ FS10; iron core magnetic circuit loss is small, to ensure the accuracy of the current transformer at 1% In.
* For measurement, the accuracy grade is 0.5S.
* Wide applicability, the sensor signal can be used for live detection, and can also be used as a signal source for online monitoring.
* Adopt "304" stainless steel clamp and lock are fastened by positioning groove to ensure reliable docking of the end face of the iron core incision after locking, and excellent excitation performance.
Product Application
It is used for supporting the transformer on the pillar of the intelligent fusion terminal in the Taiwan area. It is used for the measurement of outdoor low-voltage electrical lines and the measurement of protection circuits. Compact fully insulated ring network switchgear; combined substation and cable distribution box.
