Description

Disconnect Blade Cutout

DISCONNECT BLADE cutout adopts design feature of fuse cutout,using cooper disconnect blade to replace fuse tube, be used as a sectionalizing device(disconnect switch) on 10kv to 38kv distribution system.It installed easily and faster,more economically,takes up a minimum of space on the crossarm. Rating current 300A-400A

Product features

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.

Design feature of single vent

Our fuse cutout adopts the design feature of single vent, exhaust downwards and outwards when fuse cutout interrput. Prevent the intrusion of rainwater, avoid damage to the upper line by free gas, and this design can improve the interrput capacity.

Excellent conductivity

All copper casting part adopts bronze/brass, it has excellent mechanical strength and excellent conductivity. All contact parts be silver-plated, it adopts convex design on the contact surface, this design can reduce the contact resistance and ensure excellent conductivity. The high-strength memory cooper alloy sheets can ensure contact with lower contact smoothly and without any affecting when fuse drop out. It adopts Arc-shortening copper rod to improve the interrput capacity when shortcircuit fault.

Reliable load breaking capacity

For Loadbreak type fuse cutout, its arc chamber made of special reinforced nylon

material. It has good mechanical strength, anti-aging and flame retardant. suitable for

use the area like high ultraviolet area, high altitude area, coastal area, etc.

Relevant international executive standards

All fuse cutouts we manufacture and test according to the latest international standard

IEC 60282-2:2008 & IEEE Std C37.41-2008 & IEEE Std C37.42-2009.

  • Three IEC standards in the insulator field, led by China, have been released.
    Recently, three IEC standards on insulators, led by China for the first time, have been officially published. These standards primarily address the coupling markings, dimensions, and tests of insulator end fittings, specifically including IEC 60120:2020, IEC 60372:2020, and IEC 60471:2020. These three standards were jointly completed under the leadership and coordination of numerous experts from the National Technical Committee on Insulators of China (SAC/TC80).

  • Types & Characteristics of Surge Arresters
    IntroductionAtmospheric lightning strikes on overhead lines, bare conductors, or metallic structures in outdoor substations, as well as overvoltages caused by switching operations of equipment and networks (switching overvoltages), pose significant hazards to electrical equipment. To protect equipment and facilitate insulation coordination,surge arresters(also known as "lightning arresters") must be installed at the incoming/outgoing points of overhead lines and in close proximity to transformer

  • Fuse Wire Materials
    Characteristics and Materials of Fuse ElementsThe materials selected for fuse elements must possess a specific set of properties. They need to have a low melting point, ensuring that the fuse will melt quickly when an excessive current flows through it, thereby interrupting the circuit and protecting the electrical system. Additionally, these materials should exhibit low ohmic loss to minimize energy dissipation during normal operation. High electrical conductivity (equivalent to low resistivity

    What is Valve Type Lightning Arrester?DefinitionA lightning arrester that comprises single or multiple gaps connected in series with a current - controlling element is referred to as a lightning arrester. The gap between the electrodes blocks the flow of current through the arrester, except when the voltage across the gap exceeds the critical gap flashover voltage. The valve - type arrester is also called a gap surge diverter or a silicon - carbide surge diverter with a series gap.Construction o

    Acoustic Emission: This method can be effectively employed to detect hazardous cracks in support insulators on - site in an offline mode. It is well - suited for identifying damages caused by mechanical stress, such as fatigue - related cracks. However, it is ineffective for detecting defects like pores. Non - destructive Ultrasound: Relying on the ultrasound impulse method, this technique works offline by exciting the insulator and its defects through the injection of short acoustic impulses.

  • Why does the AC SPD fuse frequently?
    An AC surge protector (also known as a surge protection device or SPD) may frequently blow for several reasons, which can be related to design, installation, maintenance, and external environmental factors. Below are some common causes and explanations:1. Poor Quality of the Surge Protector Insufficient Voltage Rating: If the surge protector's rated voltage or maximum continuous operating voltage (UC) is lower than the actual system voltage or the highest possible fault voltage, it may be subjec
