ICEA S-73-532 THHN/THWN-2 Unscreened Control Cable 600V
ICEA S-73-532 referenced THHN/THWN-2 Unscreened Control Cable is a 600V multicore control cable using bare annealed copper conductors, PVC-FR / Nylon insulation and a black special-PVC outer sheath without an overall metallic screen. The product uses E2 core identification referenced to ICEA S-73-532 and is intended for industrial supervisory and control circuits.
PRODUCT OVERVIEW
This product is part of a control-cable system built around PVC-FR / Nylon insulated copper conductors assembled beneath an overall special-PVC sheath. The source product data identifies the core colours as E2 per ICEA S-73-532, making conductor identification one of the clearest standard-specific features for this product family.
The unscreened construction omits the aluminum tape and tinned-copper drain wire used in the screened version. It is therefore positioned for general control circuits where a dedicated overall electrostatic screen is not specified, while retaining the same 600V and 90°C product ratings shown in the source data.

SCREENED VS UNSCREENED THHN/THWN-2 CONTROL CABLE
Feature | Unscreened Type | Screened Type |
Metallic Screen | None | Aluminum tape |
Drain Wire | None | Tinned copper, 16 AWG, 7 strand |
Main Selection Reason | General control circuits where an overall metallic screen is not required | Control circuits where electrostatic interference needs to be reduced |
Construction | Simpler cable build | Additional screen and drain wire |
Overall Diameter / Weight | Generally slightly smaller and lighter | Generally slightly larger and heavier |
EMC / Interference Control | Depends on routing and system design; no overall metallic screen | Overall screen provides a dedicated electrostatic shielding layer |
Choose the unscreened version when the project does not require an overall metallic screen and cable routing is compatible with an unscreened control-cable design. Where the specification explicitly calls for shielding, or control circuits are routed near significant sources of electrical interference, the screened construction should be reviewed instead.

E2 CORE IDENTIFICATION
The product data states that core identification is colour coded as E2 per ICEA S-73-532. This is a meaningful standard-specific feature because multicore control cables depend on consistent conductor identification during panel wiring, field termination, inspection and maintenance.
For project supply, the required core-colour sequence, conductor marking and any customer-specific identification requirement should be confirmed before production, especially on higher-core-count cables.

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
Annealed copper conductors are insulated with the specified PVC-FR / Nylon system, assembled into the required flat or multicore construction, fitted with the nylon ripcord and finished with the black special-PVC sheath.
Inspection
Inspection focuses on conductor condition, insulation and nylon-layer thickness, core identification, sheath integrity, finished dimensions, cable weight and electrical requirements defined for the approved construction.
Packaging
Finished cable is wound on suitable reels or drums according to cable size, weight and ordered length. Product identification can include standard reference, AWG size, core count, length and project reference.
Shipping
Before shipment, cable identification, packing and requested technical documents are checked against the order. Project-specific inspection records or approval documents should be confirmed before production.
Frequently Asked Questions
When should I use the unscreened version rather than the screened version?
Use the unscreened version where the control circuit does not require an overall aluminum-tape screen and the installation design can manage interference without dedicated cable shielding. If the project specification requires an electrostatic screen or the circuit is sensitive to nearby electrical interference, select the screened version instead.
Is this cable suitable only for instrumentation signals?
No. The uploaded product is presented as a control cable and includes a broad multicore range. ICEA S-73-532 also covers control, thermocouple-extension and instrumentation cable families, but that does not mean every construction serves all three functions identically. Selection should follow the actual circuit and project specification.
What should I confirm before using this cable on an ICEA/NEMA project?
Confirm the required standard edition, core-identification scheme, AWG size, core count, installation environment and any required test documents. If the buyer requires specific certification or witnessed tests, those items should be stated before quotation and production.
What information should I provide for a quotation?
Provide core count, AWG size, length, installation environment and whether the project requires screened or unscreened construction. Also state E2 or other core-identification requirements, cable marking, packing length, standard edition and any inspection or documentation requirements.
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.
