thermoplastic bushing 1200A
The 1200A Low Voltage Bushing is a thermoplastic insulated through-wall bushing rated for 1.2kV systems and 1200A continuous current. It provides a safe, insulated passage for low voltage conductors passing through transformer tanks, switchgear enclosures, or generator housings.
Manufactured from high-strength thermoplastic , this bushing offers excellent dielectric properties, UV resistance, and mechanical strength at a lower cost than porcelain or epoxy alternatives. It is suitable for dry-type transformers, LV switchgear panels, generator terminals, and motor control centers.
Technical parameters:
1) Voltage class 1.2 kV, BlL 30kV, AC withstand voltage 10kV/min
2) Continuous current: 1500A
3) Application temperature -40~140℃, Indoor condition without salt fog and chemical corrosion
4) Conductor materlal: copper C11000
5) Color of insulation body: black
6) Recommended dia. of tank hole: 45.0+0.5mm
7) Sealing gasket see left vew
8) Dimensions can be changed on customer's request
All dimensions are in mm unless otherwise specified.

Q: What is the difference between thermoplastic and porcelain bushing?
A: Thermoplastic is lighter, lower cost, impact resistant, and won't shatter. Porcelain is heavier, more expensive, but has higher heat tolerance.
Q: Is this bushing suitable for outdoor use?
A: Yes, with UV-stabilized thermoplastic. Specify outdoor requirement when ordering.
Q: What is the standard terminal size?
A: M12 or M16 copper studs. Custom sizes available.
Q: Can this be used on oil-filled transformers?
A: For dry-type only. For oil-filled, specify oil-resistant gasket and material.
Q: What is the lead time for 1200A 1.2kV bushings?
A: Stock items: 3-7 days. Custom: 15-25 days.
