24kV High Voltage Disconnect Switch for Distribution Line

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.

WARM TIPS

When order,please indicate the detailed information as below listed:

1) Rated voltage and rated current .

2) Minimum creepage distance.

3) The material of insulator.

4) Please indicate whether arc-shortening rod should be fitted with fuse cutout.

5) Please indicate the type of mounting bracket.
