YGC22 Armored Silicone Rubber Cable — High-Temperature Power & Control Cable for Harsh Industrial Environments

When cable insulation fails under continuous thermal load, the result isn’t just a shutdown. It’s a cascade of unscheduled maintenance, lost production hours, and safety audits that no plant manager has time for. The YGC22 armored silicone rubber cable is engineered to remove that variable. It delivers stable power and control transmission in environments where standard PVC or XLPE cables degrade within months. This is a cable built for sustained exposure to heat, oil, moisture, and mechanical stress — without the constant replacement cycle that eats into your operational budget.

Key Technical Advantages That Reduce Total Installed Cost

Silicone Rubber Insulation and Sheath — Maintains Flexibility After Heat Aging

Conventional cables embrittle when the plasticizer evaporates at high temperature. Silicone retains its elastic properties from -60°C to +180°C, with short-term spikes up to 200°C depending on the compound.
This means fewer conductor fractures at termination points. Your maintenance crew isn’t re-terminating cables every quarter because the insulation cracked at the bend. In steel mills, foundries, and glass plants, that directly reduces unplanned work orders.

Galvanized Steel Tape Armor — Mechanical Protection Without Conduit Cost

A layer of galvanized steel tape sits between the inner sheath and the outer jacket. It protects the cores from crushing, impact, and accidental penetration.
You skip the separate steel conduit in many indoor tray and direct-burial applications. That removes a line item from your BOM — fewer materials, fewer man-hours, shorter installation window. For project engineers optimizing per-meter costs, this armor layer often becomes the deciding factor in cable selection.

Dry-Type Core Construction — No Gel, No Migration

Unlike older compound-filled cables, the YGC22 adopts a dry construction. No filling gel leaks out at high temperature when the cable is routed vertically.
That keeps termination enclosures clean. It also eliminates the periodic gel top-up that compound-filled armored cables demand in vertical risers. For procurement managers tracking total lifecycle cost, a dry core removes one hidden maintenance ritual.

Tinned Copper Conductors — Resistance to Oxidation Under Thermal Cycling

Tinned copper is standard. Bare copper oxidizes faster under repeated heating and cooling, increasing contact resistance at lugs and terminals.
Tinning preserves low resistance long-term. You avoid hotspots at connection points, which are among the most common root causes of thermal imaging alerts in preventive maintenance reports. A single avoided call-out can cover the marginal cost difference between tinned and bare copper many times over.

Custom Core Configuration — Exactly What the Panel Drawing Requires

There is no fixed production table you’re forced to design around. Cross-section, core count, shield type (copper braid, copper tape, or combination), and outer jacket colour are specified per order.
You receive a cable that matches your switchgear or motor terminal layout directly — no adapting terminations to off-the-shelf limitations. This reduces engineering changes during the electrical design phase and shortens panel shop lead times.

Industry Applications & Scenario Validation

• Steel Mills & Non-Ferrous Metal Smelters
  Routed near ladle turrets, casting platforms, and reheat furnaces. This cable handles radiant heat that softens PVC within hours. Silicone insulation eliminates insulation slump in vertical trays near hot zones.

• Glass Manufacturing Plants
  Feeder channels and Lehr conveyor drives require cables that sustain flexibility at temperatures exceeding 150°C continuously. YGC22 is specified here precisely because standard EP rubber cables harden and crack under the same exposure.

• Petrochemical & Refinery Projects
  Areas where cables are subject to both heat and occasional mineral oil splash. The combination of silicone outer jacket and steel tape armor meets this dual stress without requiring an external oil-resistant conduit wrap.

• Power Generation — Waste-to-Energy & Biomass
  Ash handling and boiler island instrumentation demand cables that survive frequent thermal cycling. The dry core construction avoids gel migration, a failure mode repeatedly flagged in post-mortem reports on standard compound-filled armored cable in vertical sections.

• Tunnel & Underground Infrastructure
  Direct burial in traction power supplies or tunnel lighting circuits where high ambient rock temperature and groundwater are present. The armor provides the mechanical layer a double-jacket cable would need an external pipe to achieve.

International Compliance & QA Standards

Procurement approval usually depends on these. YGC22 production is audited against the following frameworks; batch-specific certificates are available with each shipment.

• ✅ IEC 60228 — Conductors of insulated cables (class 2 and class 5 flexible as required)
• ✅ IEC 60332-1-2 — Flame retardance for single vertical wire
• ✅ HD 308 S2 — Identification of cores (color coding per European practice or customer spec)
• ✅ CE Marking — Cable complies with Low Voltage Directive 2014/35/EU
• ✅ RoHS 2 (2011/65/EU) — Silicone compound and tinning materials are RoHS-compliant
• ✅ ISO 9001:2015 — Cable manufacturer’s quality management system certification
• ✅ EN 50525 series — Applicable tests for low-voltage power and control cables (built on request)
• ✅ Test Reports — Routine electrical test (spark test, voltage test), material elongation and tensile before and after aging, hot-set test for silicone

If your acceptance criteria reference a specific clause under IEC 60502-1 or VDE 0250, include it in the RFQ. Custom testing can be bundled in the order.

FAQ

Q: We need this cable for vertical cable tray runs inside a blast furnace area. How do you prevent insulation migration over time?
A: The YGC22 uses a thermoset silicone compound that does not melt or drip, and the construction is dry — no filling compound to migrate. We also apply a textile binder tape between the inner sheath and armor that adds mechanical grip. In practice, cables installed vertically at 180°C continuous have shown less than 3% jacket slippage over 24-month inspection intervals. That’s functionally zero maintenance on vertical segments.

Q: Can you supply a version with overall copper tape screen plus steel tape armor for VFD motor connections?
A: Yes. We frequently manufacture a configuration with tinned copper tape screen (100% coverage or overlapped) applied over the individual cores or over the core assembly, followed by a separator, then the galvanized steel tape armor. This screen drains common-mode noise to ground and keeps bearing currents in check. The cross-section of the copper screen is sized per your inverter rated current and cable length. Specify “YGC22 with overall copper tape screen” in the inquiry and we will return a drawing.

Q: What’s your typical delivery lead time for custom core counts, and are mill test certificates included?
A: For standard core/cross-section combinations with stock raw materials, 12–16 working days from drawing approval. Non-standard shield configs or large conductor sizes (over 95 mm²) usually add 5–7 days. Every shipment includes a digital copy of the routine test report and material traceability certificates. With advance planning, we hold emergency buffer stock for commonly specified YGC22 builds used in steel plant and foundry maintenance shutdowns — express dispatch can drop to 5 working days in those cases.
