High-Temperature and Oil-Resistant Wiring Tips for ZCEBOX Plastic Distribution Box Junction Boxes in Commercial Kitchens

Nov. 17, 2025

In commercial kitchen scenarios (restaurant back kitchens, central kitchens, food processing plants), junction boxes need to withstand high-temperature radiation from stoves, heavy oil contamination, steam condensation, chemical cleaner corrosion and kitchen equipment vibration, and are prone to problems such as oil blockage, insulation aging, seal failure and terminal corrosion. ZCEBOX shares 2 targeted adaptation tips that comply with commercial kitchen electrical safety standards (GB 4706.1, IEC 60529):

1. Core Protection Design for High-Temperature and Oil-Resistance

Model Adaptation: Prioritize ZCEBOX commercial kitchen-specific models (temperature resistance range -20℃~120℃, short-term resistance to 150℃ high-temperature radiation), with box body made of flame-retardant and oil-resistant modified PP + glass fiber material (flame retardant grade UL94 V-0, oil resistance compliant with ISO 1817) and protection grade IP65+ to resist oil contamination and steam intrusion;
Material Upgrade: Use kitchen-specific oil-resistant and high-temperature-resistant cables (insulation layer made of XLPE cross-linked polyethylene material, oil resistance ≥ Level 4, temperature resistance 125℃); power wires (kitchen equipment power supply) have a diameter ≥2.5mm², and signal wires (thermostat, fan control wires) adopt oil-resistant shielded wires with a shielding layer grounding resistance ≤1Ω to avoid signal interference caused by oil wrapping;
Sealing and Anti-Sticking: Use oil-resistant silicone rubber sealing strips (Shore hardness 55±5, resistant to kitchen mineral oil and cleaner erosion) for box joints; install oil-resistant quick connectors (with built-in anti-sticking sealing rings, suitable for 2-6mm² wires) at wiring holes; spray nano anti-stick coating (thickness ≥30μm) on the box surface, allowing oil contamination to be directly wiped with a damp cloth to avoid accumulation blocking heat dissipation holes.

2. Vibration Resistance, Corrosion Prevention + Convenient Maintenance Optimization

Vibration-Resistant Fixation: Near vibration equipment such as stoves and fans, use ZCEBOX kitchen-specific buffer mounting brackets (with built-in nitrile rubber buffer pads, thickness 8mm), reserve a 5mm buffer gap between the box and the mounting surface to absorb kitchen equipment operation vibration; tighten terminals to 1.2-1.5N·m torque and install anti-loose washers; fix wires with oil-resistant cable ties every 30cm to avoid loose wiring caused by vibration;
Corrosion Prevention Enhancement: Select 304 stainless steel corrosion-resistant terminals (or gold-plated contacts, contact resistance ≤8mΩ) to resist corrosion from cleaners (e.g., strong alkali, chlorine-containing cleaners); spray food-grade anti-corrosion coating (compliant with FDA 21 CFR Part 175 standard) inside the box to cover terminals and wiring parts, isolating steam and oil contamination;
Convenient Maintenance: Adopt quick-release buckle design (opening the cover in 5 seconds without tools), with laser-etched marks next to terminals (resistant to repeated wiping without fading); reserve a hidden cleaning window on the side of the box; regularly rinse with neutral detergent (e.g., dish soap solution) and purge through the window with dry compressed air (0.2MPa) without removing wires; equip oil-resistant sealing plugs for idle wiring holes to prevent oil entry.

Adapting to the harsh working conditions of commercial kitchens, balancing high-temperature resistance, oil resistance, corrosion prevention and maintenance convenience, ensuring safe and stable operation of kitchen electrical equipment.
