The?Main?Features?Of?Embedded?Pole

◆High?Reliability?And?Stability

Compared?with?assembly?pole, ?embedded?pole?use?much?less?spare?parts, ?conductor?faying?surfaces?and?jointing?fastening?piece, ?so?that?simplify?the?conductance?circuit’s?assembly?links, ?lower?the?circuit’s?resistance?and?improve?galvanic?circle’s?reliability?and?stability.

◆Stable?Insulating?Ability

Vacuum?interrupter?embedded?with?epoxide?resin?solid?material, ?guarantee?the?minimized?affection?from?external?environment, ?and?its?external?insulating?ability?will?avoid?the?influence?from?dust, moisture, small?animal, condensation?and?filthy, fully?satisfy?requirements?of?GB/DL?standards?of?secondary?filthy?area.

◆Firm?Struction

It?will?give?more?sufficient?protection?for?vacuum?interrupter., free?of?mechanical?collision?in?process?of?assembly?and?transportation.

◆Miniaturization

Its?insulating?media?is?epoxide?resin, ?pole?to?pole?distance?will?shorten, ?using?less?vacuum?circuit?breaker’s?space.

◆Free?Maintenance?

Because?the?whole?pole?embedded?to?overall?part, ?vacuum?interrupter?gets?fully?protection, ?vacuum?interrpter’s?free?maintenance?also?benefit?the?circuit?breaker’s?free?maintenance.

◆More?Environment?Protection

To?some?degree, ?embedded?pole?circuit?breaker?will?take?over?SF6, ???so?it?is?more?environment?friendly.
