Product features
High performance of weather aging resistance
-
For porcelain insulator, the porcelain body connects with hardware fitting by cement pouring, we use the (Prorok)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 molded 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 interrupt. Prevent the intrusion of rainwater, avoid damage to the upper line by free gas, and this design can improve the interrupt capacity
-
It adopts Arc-shortening copper rod to improve the interrupt capacity when short circuit fault.
Excellent conductivity
-
All copper casting parts adopt bronze/brass, it has excellent mechanical strength and excellent conductivity.
-
All contact parts are 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 drops out.
Reliable load breaking capacity
For Load break 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 areas, high altitude areas, coastal areas, etc.
Relevant international executive standards
We manufacture all fuse cutouts and test according to the latest international standard IEC 60282-2:2008 & IEEE Std C37.41-2008 & IEEE Std C37.42-2009.
