... Z 123-T; Z 123.OS-A a Z 123.T-A jsou jednopólově zapouzdřená elektrická zařízení pro napětí 123kV, izolovaná plynem SF6, která umožňují připojení kabelů vvn k silovým transformátorům.
Poznámky redaktora
T cable bushing end connections have been designed for the connecgtion
of SILEC-type cable, with SILEC cable termination CEI 859; 11274 type.
The cable bushing end connection for 110 transformers, type ZAU 123.g.OS and ZAU 123. another variation, e.T-A cable bushing end connections are designed for the connection cables, provided with
SÜD KABEL cable termination EHSVS 72. nebo jiné

flange connections provide for adequate current conductivity. the same way also the connection the bushing the 110 transformer arranged.
The SF6 pressure sensor provided with two indication steps: the first one 0. rovněž možné dodat zaústění kabelů uzemňovačem ovládaným ruční odnímatelnou pákou (
s možností uzamčení poloh „zap“ nebo „vyp“), typovým označením ZAU 123.T-A, shown in
Figures 1/2, respectively.C.U viz obr.5/123/145 type.
The ZAU 123.
Each assembly set the cable bushing end connection provided with safety break-through membrane,
protecting the set against dangerous rise gas pressure, with manometer (temperature compensated
pressure sensor) for indication purposes, and filling valve used for the evacuation the device before
filling with SF6 the operation pressure level. The ZAU 123. Connection between the above part and the
transformers occurs through the SF6/oil bushing EKTG 550/123-1000 type, manufactured the
company HOCHSPANNUNGGERÄTE PORZ GMBH. The connecting material made stainless steel.
The both sleeves are coupled with each other using gas-tight screw-type flange connections, sealed with
„O“ rings.01/2017
