JQJL04(11JB)-2010 JB-type سلك التلامس مشبك التوصيل
المواصفات الفنية
| الطراز | JQJL04(11JB)-2010 |
|---|---|
| المعيار | TB/T 2075Series standards |
| الخامات | سبيكة النحاس مشبكs with soft copper كابل التوصيلs |
| التركيب | joints between الحبل الحامل and سلك التلامس, at قسم الشد joints and تقاطعs |
The JB-type سلك التلامس مشبك التوصيل (drawing No. JQJL04(11JB)-2010) serves joints between كابل التوصيلs and سلك التلامسs in electrified شبكة التلامس systems, in CuNi2Si/T2 by die forging.
Excellent mechanical and electrical performance: slip load between the مشبك and the سلك التلامس at least 4.0kN, ampacity not lower than the rated ampacity of the joined wire — safe and reliable in service.

الأداء
ظروف التشغيل
For all conductive nodes of the شبكة التلامس, ensuring smooth traction current return.
الأداء الميكانيكي
The مشبك grips reliably without damaging the wire; the كابل التوصيل is soft and bend-tolerant.
الأداء الكهربائي
Low transition resistance; ampacity satisfies traction current requirements without overheating in long-term service.
التطبيقات
Tension length joints:
JB-type مشبكs (JQJL04(11JB)-2010) ensure electrical continuity across قسم الشدs.
Turnout areas:
JB-type مشبكs provide equipotential bonding between شبكة التلامس legs at تقاطعs.
Mainline suspension points:
JB-type مشبكs split current between الحبل الحامل and سلك التلامس on mainlines.
Feeder nodes:
JB-type مشبكs carry high current at feeder introduction points.
