UL 1277 FR-XLPE LCT Shielded CPE Control Cable 600V
UL 1277 FR-XLPE LCT Shielded CPE Control Cable is a 600V multi-conductor industrial control cable with Class B compressed bare-copper conductors, flame-retardant XLPE insulation, a 5 mil LCT tape shield and a chlorinated-polyethylene (CPE) outer jacket. It is intended for wet and dry industrial control-cable routes where UL 1277 tray-cable construction, shielding and robust thermal performance are required.
PRODUCT OVERVIEW
The cable uses 7-strand Class B compressed bare-copper conductors insulated with 30 mil FR-XLPE. Polypropylene filler is used on constructions with five or fewer conductors, while cables with more than five conductors use a polyester flat-thread binder. A 5 mil LCT tape shield surrounds the cabled core, followed by a rip cord and an overall CPE jacket.
The product is rated 600V and is suited for wet and dry areas, conduits, ducts, troughs, trays, direct burial and aerial routes supported by a messenger. The source lists 90°C for normal operation, 130°C for emergency overload and 250°C for short-circuit conditions. UL-rated constructions may be used in Class I, II and III, Division 2 hazardous locations, while constructions with three or more conductors are stated as listed for exposed runs (TC-ER).

WHY LCT SHIELDING?
The defining difference between this construction and an unshielded control cable is the 5 mil LCT tape shield. The shield creates a dedicated metallic layer around the multicore assembly, making this product appropriate where the project specification calls for a shielded control-cable construction.
The source does not state the LCT material composition, shield coverage percentage, drain-wire construction or a specific grounding method. Those details should therefore be confirmed with the manufacturer whenever the project has a defined EMC, shield-termination or grounding requirement.
SHIELDED VS UNSHIELDED FR-XLPE / CPE CONTROL CABLE
Feature | Shielded Type | Unscreened Type |
Metallic Shield | 5 mil LCT tape shield | No shield layer |
Primary Selection Reason | Projects requiring a shielded control-cable construction | General control circuits where overall shielding is not required |
Cable Build | Additional shield layer between core assembly and outer jacket | Core assembly followed by outer jacket |
Engineering Review | Shield material / termination / grounding requirements should be confirmed | Routing and interference conditions should be checked without an overall screen |

Request the Complete Data Sheet
From Production to Delivery
From raw material preparation to final shipmen, every stage is caretuly controled to ensure consistent conductor quality, reliable pertormance,and sae delivery. Our roduction,
inspection, packaging, and logistics processes are managed in accordance with applicable standards and project requirements.
Production
Class B compressed bare-copper conductors are prepared, insulated with FR-XLPE, assembled with polypropylene filler or polyester binder according to core count, wrapped with the specified 5 mil LCT tape shield, fitted with the rip cord and finished with the CPE jacket.
Inspection
Inspection focuses on conductor construction, insulation/jacket thickness, shield application, overall diameter, conductor and cable weight, DC/AC resistance, bending-radius data, cable marking and project-specified documentation.
Packaging
Finished cable is wound on reels or drums suitable for its diameter, weight and ordered length. Product identification can include conductor size, core count, standard reference, length and project number.
Shipping
Before shipment, cable marking, packing, inspection records and requested standard/test documents are checked against the order and project approval requirements.
Frequently Asked Questions
When should I choose this shielded version instead of the unshielded FR-XLPE/CPE control cable?
Choose the shielded version when the project specification calls for an overall shielded control-cable construction or when the engineering design requires a metallic screen around the multicore assembly. The source specifies a 5 mil LCT tape shield. If shielding is not required, the unshielded construction may be simpler.
What details about the LCT shield should be confirmed before ordering?
The source states only that the cable has a 5 mil LCT tape shield. It does not define the tape material, coverage, drain wire or grounding method. If the project has specific EMC, continuity, grounding or termination requirements, those items should be confirmed with the manufacturer before quotation.
What should I verify if TC-ER is required?
The source states that UL-rated constructions with three or more conductors are listed for exposed runs. Confirm that the exact conductor size and core count being supplied carries the required TC-ER marking/listing rather than relying only on the family description.
Can this cable be used in hazardous locations?
The source states that UL-rated constructions can be used in Class I, II and III, Division 2 hazardous locations. The complete installation still depends on cable marking, fittings, seals, wiring method and the governing NEC/project requirements.
How should the 60°C, 75°C and 90°C ampacity columns be used?
Use the column appropriate to the permitted conductor/termination temperature in the project design, then apply any code-required derating for ambient temperature, grouping and installation conditions. The listed values are product data, not a substitute for the governing electrical-code calculation.
What products do you supply for the power cable industry?
We provide a wide range of cable materials and electrical products, including aluminum conductors, aluminum rods, aluminum wires, overhead conductors, medium and low voltage power cables, cable insulation materials, filling materials, shielding materials, and cable manufacturing consumables.We provide customized solutions according to different cable manufacturing requirements.
