Power cable YJV22

oil-resistantchemical-resistantflame-retardant

Overview
The YJV22 is an armored power cable with a copper conductor, XLPE insulation and galvanized steel-tape armor with a flame-retardant PVC outer sheath. It is designed for buried, ducted or trench-laid fixed installations and for industrial power distribution at AC 0.6/1 kV. The construction provides mechanical protection and stable thermal performance for underground infrastructure and heavy-duty routing.

Application

• Power supply for distribution networks, industrial equipment and underground installations in infrastructure and plant environments.

Materials & Standards

• Materials: Conductor — high-purity oxygen-free copper; Insulation — cross-linked polyethylene (XLPE); Armor — galvanized steel tape; Outer sheath — flame-retardant PVC resistant to moisture, oils, acids and alkalis.
• Standards: Manufactured to GB/T 12706 series with referenced IEC compatibility for 0.6/1 kV class.

Operating Characteristics

• Long-term operating temperature: ≤ 90°C.
• Cable-laying ambient temperature: ≥ 0°C.
• Bending radius: Flexible cable — D < 25 mm: ≥ 4D; D ≥ 25 mm: ≥ 6D.
• Short-circuit withstand (brief): suitable for short-time fault conditions (brief temperatures up to approximately 250°C as per product specifications).
• Structure: Copper conductor + XLPE insulation + inner sheath + galvanized steel-tape armor + flame-retardant PVC outer sheath.

Typical sizes & electrical parameters (examples)

• 2×1.5 mm² — Finished OD 13.3 mm — R20 max 12.1 Ω/km — Reference current 19 A
• 2×2.5 mm² — Finished OD 14.1 mm — R20 max 7.41 Ω/km — Reference current 26 A
• 2×10 mm² — Finished OD 19.5 mm — R20 max 1.83 Ω/km — Reference current 63 A
• 2×16 mm² — Finished OD 21.5 mm — R20 max 1.15 Ω/km — Reference current 85 A

Key Features & Notes

• Galvanized steel-tape armor provides mechanical protection against crushing, impact and rodent damage — suited to buried or heavily loaded routes.
• XLPE insulation improves dielectric strength and thermal endurance with low dielectric loss under continuous load.
• Flame-retardant PVC outer sheath resists moisture, oils, acids and alkalis for corrosive or humid environments.
• Designed for underground power delivery in infrastructure, industrial sites and community networks where long service life and mechanical protection are required.
