12kv High Voltage Disconnect Switch for Distribution Line
12kv High Voltage Disconnect Switch for Distribution Line image
STANDARD Fuse Cutout
Provide protection to the line of distribution system and the various apparatus on those line such as transformers and capacitor banks.It can also be used as a sectionalizing device.Using aportable loadbreak tool,it can function much like an overhead line disconnect switch.
Maximum design voltage from 10Kv-38kv;Maximum Rating current 100-200A
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.
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.
