Ó lè pa ní àárín àti tó lè gba grounding switch ní ọ̀pọ̀lọpọ̀ tàbí mẹ́ta. 90°drive's isolating switch and grounding switches ń lo cs11 manual operating mechanism fún trí-pole linkage; 180°drive's isolating switch ń lo CS11 manual operating mechanism tàbí CS14g manual fún trí-pole linkage; grounding switch ń lo CS11 manual actuator fún trí-pole linkage.

DS5A Switch Disconnector ní àwọn single poles mẹ́ta àti actuator. Ọ̀kan pàtàkì pẹ̀lú base, post insulator àti conductive part. Mẹ́ta pẹ̀lú post insulators méjì ń wá ní base níbi tí àwọn insulators ní ọ̀nà V shape.

Awọn ẹ̀ka pàtàkì:

• Conductive arm tí ó ń lo rectangular Al-alloy pipes jẹ́ ẹ̀ka fún high strength, light, weigh, large radiation area àti strong resistance against corruption.
• DS5A ń lo particular copper alloy fún self-contained contact. Contact point ń sì pa lẹ́yìn elastic force of the contact itself. Contact spring ń pa padà láti idajọ́ drop of the contact in gripping force nítorí spring's corrosion àti shunting, possible heating and annealing, possible increment in contact resistance, àti vicious cycle of the growing heat or the contact. Contact ń lo curved copper plate, fún large connection area with the conductive arm. Nínú opening àti dosing processes, ó ń wá ní short trip of friction between the contact and the finger, àti required operating force is small. Conductive part ti di acknowledged by the Chinese competent authority as a new and practical patent.(Patent No.: 2103 2 20022.6)
• Rotating parts of the Switch Disconnector ń lo design free of maintenance. Rotating base ń lo closure structure láti denà access of moisture, dust àti harmful gases, bíi diẹ̀ nínú low-temperature lubricating cream within the bearing will not run off or harden. Within the bearing base are thrust ball bearing and radial ball bearing, both of which will share the gravity and horizontal component of the Switch Disconnector so that the operating torque will not increase after the long-term operation of the disconnect switch
• Mechanical interlock between the primary switch and earthing switch ń lo direct installation onto the principal axis of the primary switch and the revolution axis of the earthing switch. Interlock Is direct and reliable, eliminating the structurally complex gearbox. It also facilitates easy adjustment In the field erection and avoids the corrosion of the gear box.
• Provide one-key sequential control "double confim1ation" function expansion
