The RO-4 insulator is designed for insulating and securing electrical wiring in buildings with a nominal network voltage up to 380 V and a frequency up to 60 Hz. It is widely used in open retro-wiring systems, providing reliable fixation and electrical insulation of wires.

Technical Specifications:

• Nominal Voltage: up to 1 kV.
• Climatic Version: U3.
• Weight: 0.012 kg.
• Material: ceramic (porcelain).
• Dimensions: base diameter — 20 mm, height — 23 mm.

Advantages:

• Provides reliable insulation and fixation of wires.
• Resistant to mechanical damage and environmental influences.
• Complies with TU and GOST requirements.

Installation:

RO-4 insulators are attached to wooden or concrete bases at intervals of 30–50 cm. The recommended consumption is about 250 pieces per 100 meters of wiring.
