Quick Detail:

1. Isolating switch, isolation switch, isolator

2. Silicone insulator

3. Rated voltage: 11kV 12kV

4. Rated current: 630a 900a

Description:

YDDCD outdoor disconnect switch is used in 12kV power distribution system, rated current 630A or 900A, short-time withstand current 25kA/3S, peak withstand current 63kA. Frequency and lightning impulse withstand voltage can reach the level of 2000 meter above sea level. It should be operated under no load conditions.

1.Terminal pad (standard): high conductively silver - plated copper, oxidating resistant, remain silver to silver contact

2.Back-up Springs (Standard): two stainless steel springs for high strength and superior corrosion resistance

3.Loadbreak Hooks (Standard): zinc - galvanized steel for corrosion protection, suitable for portable loadbreak tool.

4.Pulling loop and latching device (standard): equipped with the cast copper latch, can operate the switch in any angle

5.Copper Blade (Standard): the double deck blade processed with hard - drawn technology for superior stiffness

6.Stainless steel pin (Standard): Stainless steel pin can position the blade at 90Oor 160O, 160O as original stand

7.90 and 160 Angle  Open Position Latch (Optional): adjustable at the position in the 90 or 160 Angle

8.Terminal pad (standard): high conductively silver - plated copper, oxidating resistant, remain silver to silver contact

9.Insulators: can provide three kinds of insulator i.e. silicone rubber, epoxy resin, porcelain

10.Installing plate: are hot dip galvanized and provide with many sizes to suit for different spaces for installation.

11.Serrated Slots (Standard): equipped with bolt and provide many sizes to suit different spaces for installation.
