Product Overview
Splice clamps are designed and manufactured by Henan Chuangwit Railway Equipment Co., Ltd. to railway industry standards for mid-line splicing of contact wires and messenger wires in electrified railway OCS, in two types: messenger wire splice clamps and contact wire splice clamps. Drawing numbering: contact wire splice clamps 9-1A (eight-bolt type, for 120/150mm²), 9-1B (eight-bolt type, for 120mm²) ; messenger wire splice clamp 9-2 (for 70/95/120/150mm², aluminum bronze QAl9-4 body+wedge and wedge sleeve).
Key Features
- Butt structure is smooth without hard points
- Meets both strength and conductivity requirements
- Simple erection tools
- Suited to emergency repair and permanent splicing
- Drawings cover 9-1A120, 9-1A150, 9-1B120 and 9-2 (70/95/120/150)
Compliance & Quality Control
The products comply with the TB/T 2075 series of standards; mechanical strength is at least 95% of the joined wire, and the splice surface is smooth so as not to obstruct pantograph passage. Electrical performance is excellent, with joint resistance no greater than an equal length of wire. The company holds CRCC railway product certification and ISO9001 quality management system certification; every piece (batch) is delivered only after passing factory inspection.
Operating Conditions & Typical Applications
For mid-line wire splicing and breakage repair joints. Typical applications include mid-line wire joints, breakage repair, and mainline contact wire and messenger wire splices.
Selection & Service
Backed by 15 years of R&D and manufacturing experience in railway electrification equipment, the company provides full life-cycle support covering selection, customization, supply and after-sales service, serving more than 20 railway administrations and multiple urban rail lines nationwide.
