Reinforced Anti-Pollution Porcelain Suspension Insulator

The U120BP/146 model combines a 120 kN rated electromechanical failing load with a 450 mm creepage distance for suspension or tension positions on medium- and high-voltage overhead lines.
A 280 mm disc diameter and 146 mm structural height provide clear dimensions for checking an existing insulator string, fittings, and installation space.
The Reinforced Anti-Pollution Porcelain Suspension Insulator is intended for projects where mechanical loading and pollution-related external insulation must be considered together.

Connection Mark and Engineering Match
 

The confirmed connection mark for U120BP/146 is 16, an important reference for steel pin/steel cap interface matching in disc suspension assemblies.

Common ball-and-socket connection marks listed in the source include 11, 16, 20, 24, 28, and 32; common clevis types include 16C and 20C.

The actual connection form and size should be checked against the selected model and project fittings.

Prototype-to-Production Support

 

OEM/ODM production can follow technical drawings or a physical prototype, with sample arrangement available before a volume order.

Structural dimensions, mechanical grade, and installation requirements can be reviewed during technical communication.

Jiangxi Xinhuang Electric Co., Ltd. has an in-house R&D team that can participate in technical coordination for customized projects. Custom sample development is stated as 30 working days.

Mechanical and Electrical Verification

 

Production covers porcelain raw-material treatment, forming, glazing, firing, and performance inspection.

Inspection resources include a universal testing machine, creepage-distance measuring equipment, hot-and-cold test equipment, and power-frequency breakdown equipment.

Finished units receive 100% inspection before packing, and buyers may appoint a third party for inspection.

Commercial Coordination

 

Standard orders generally require 30 days for production, while customized orders generally require 45 days. Photo or video progress updates can be supplied.

EXW, FOB, and DDP terms are supported, and export packaging follows destination-country receiving requirements.

Standard orders use 30% advance payment and 70% balance payment; customized orders use 70% advance payment and 30% balance payment.
