PVC Shielded vs PUR Shielded Drag Chain Cable

FAQ

Q1: What is PVC shielded drag chain cable used for?

A1: It is a medium-flex continuous motion control cable with full shielding, mainly used for signal transmission of moving automation equipment, effectively preventing electromagnetic interference and ensuring stable control signal output.

Q2: How many bending cycles can PVC shielded towline cable support?

A2: Standard industrial grade reaches up to 5 million bending cycles, suitable for most medium-frequency reciprocating drag chain working conditions.

Q3: Is PVC shielded drag chain cable better than PUR cable?

A3: Not exactly. PVC version is more cost-effective for standard indoor environments; PUR version has better oil resistance, low temperature performance and longer lifespan for harsh high-frequency motion scenarios.

Q4: Why use shielded drag chain cable for automation?

A4: Industrial workshops have strong electromagnetic interference from inverters and servo motors. The shielding structure stabilizes weak control signals and avoids equipment misoperation or alarm faults.

Q5: Can you supply custom core count and length?

A5: Yes. We support multi-core customization, arbitrary length cutting and pre-assembled connectors, with free samples and factory wholesale price.
