Product Overview
The messenger wire mid-point anchor clamp (BJL0503E) produced by Henan Chuangwit Railway Equipment Co., Ltd. anchors 85-150mm² contact wires to 70-120mm² messenger wires — anti-creep and reliable in service.
Key Features
- reliable gripno slip
- dual anti-break and anti-creep function
- common erection tools, easy erection
- setscrew/reinforced type with multiple structures
Compliance & Quality Control
Complies with TB/T 2075 (electrified railway OCS fittings) Series standards, the clamp grips firmly without damaging the wire, overall strength not lower than the rated load of the fixed wire; the anti-loosening structure suits long-term vibration. low transition resistance ensures electrical continuity across the tension length. 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 the middle of tension lengths of all contact suspension types, , locking the expansion zero point and preventing breakage snatching and temperature creep. Typical applications include: Mainline tension length mid-points:, Long tension lengths:, Graded sections: and Bridge and tunnel sections: etc..
Selection & Service
We provide selection verification and non-standard customization based on line conditions and operating parameters, Products follow CRCC railway product certification and ISO9001 quality management system requirements; key parameters are verified by factory inspection and type tests.

Applications
Mainline tension length mid-points:
messenger wire mid-point anchor clamps lock the longitudinal zero of the OCS.
Long tension lengths:
they prevent accumulated temperature creep on long tension lengths.
Graded sections:
they prevent wire creep down the gradient on graded sections.
Bridge and tunnel sections:
they secure longitudinal stability in bridge and tunnel sections.
