16A 250V Waterproof Extension Socket with Plug & Cable

1. Product Description

The SY-CZ-61 waterproof extension socket is a heavy-duty extension cord that delivers safe, dependable 16A 250V power wherever fixed wall outlets are out of reach. Engineered by Zhejiang Shuangyang Group (Soyang), one of China's leading power cord and extension socket manufacturers, this extension socket with plug combines a durable European plug, a flexible rubber-insulated cable and an IP44 splash-proof socket with a flip-lid cover. Whether you are running power tools on a job site, powering machinery in a workshop, or extending a circuit across a warehouse, the SY-CZ-61 gives you a stable, long-life power connection you can rely on.

2. Core Advantages / Key Features

• IP44 waterproof flip-lid socket – The spring-loaded hinged cover protects the contacts from dust and water splash, making the extension socket safe for outdoor, garden and damp environments.
• Industrial-grade 16A 250V rating – Generous current capacity supports heavy-duty tools and appliances while reducing heat build-up and voltage drop over long cable runs.
• Durable European plug – A precision-moulded plug with earth contact locks firmly into standard European sockets for a secure, low-resistance connection.
• Flexible, oil-resistant cable – Available in H05RN-F / H07RN-F rubber cable (3G 1.0–2.5 mm²), the cord stays flexible even in cold weather and resists oil, moisture and abrasion.
• Flame-retardant housing – Impact-resistant engineering plastic gives the socket high mechanical strength and a long working life in harsh conditions.
• Fully customisable – Cable length, wire gauge, plug type, socket style and colour can all be tailored to your project or brand.

4. Materials & Finish

Every component is selected for safety and longevity. The housing is moulded from flame-retardant engineering plastic that resists impact, heat and UV, holding its shape and colour through years of heavy use. Inside, high-conductivity copper conductors ensure stable current flow with low resistance, while the flexible rubber insulation delivers excellent heat, oil and abrasion resistance. The corrosion-resistant contacts are shaped for a firm grip, keeping the extension socket reliable through thousands of plug-in cycles.

5. Application Scenarios

• Workshops & garages – Power grinders, drills, bench tools and machine lighting without hunting for a free outlet.
• Construction & job sites – Run a temporary, dependable power supply for site tools and lighting.
• Outdoor & garden – Connect watering pumps, lawn mowers and garden lights to a splash-protected extension socket.
• Warehouses & factories – Extend power to workstations, machinery and production lines.
• Homes & offices – Reach appliances, chargers and small equipment in hard-to-reach corners.
