适合您应用的 IP68 防护外壳

目前市场上 IP68 电气外壳的一些基本类型包括

IP68 electrical enclosures are rated for continuous immersion — equipment that lives underwater or in flood zones: submersible pump connections, wet-well controls, underwater lighting junctions, dockside and marine instrumentation, and any installation where standing water is a design condition rather than an accident. Under IEC 60529, IP68 means the ingress of water in harmful quantity is prevented during prolonged immersion at conditions agreed between manufacturer and user.

We build IP68 enclosures with welded or molded bodies, engineered seals, and entry systems that keep the rating after cabling. ElectricalCabinet has built electrical enclosures and control systems since 2010, delivering more than 4,000 projects for industrial clients. Our fabrication covers CNC punching, bending, and welding, with custom cutouts, sizes, and surface finishes built to your drawings. The cable entries and potting details are specified together with the box — immersion duty is won or lost at the glands, not the shell.

IP68 防护外壳的特点

  • 防护等级 (IP) IP68 中的 "IP "指入侵保护，"68 "代表保护级别。第一个数字 "6 "表示完全防尘。第二位数字 "8 "表示防止长时间浸入一米深的水中，具体由制造商说明。
  • 防尘保护： IP68 防护等级的外壳可提供全面的防尘保护，确保灰尘不会进入封闭的设备。
  • 水资源保护： 这些外壳可提供强大的保护，防止设备持续浸泡在水中，因此适用于设备可能长时间浸泡的场所。
  • 建筑： 这些外壳通常由不锈钢、铝或增强塑料等坚固材料制成，可以承受最恶劣的天气条件，同时提供长期保护。

IP68 防护等级的优缺点

优势

  • 全面保护： 提供最佳的防尘和防连续浸水保护，从而保证所含设备的使用寿命和运行。
  • 用途广泛： 适用于室内和室外的广泛用途，在最苛刻的环境中也能适应使用
  • 耐用的结构 采用坚固材料设计，可抵御恶劣环境，提供持久保护，结构经久耐用。

缺点

  • 费用 IP68 防护等级的外壳具有很高的防护等级和坚固的结构，这意味着它们的成本可能会更高。
  • 安装注意事项 要保持 IP68 认证并确保完全保护取决于正确的安装。

定制您的 IP68 防护外壳

我们定制的 IP55 防护罩可提供可靠的防尘和低压水射流保护，因此非常适合室内和室外应用。有多种尺寸、材料和附加功能可供选择，确保您的电气设备在任何环境下都能得到保护。

常见问题

What exactly does the 8 in IP68 guarantee?

It guarantees protection against continuous immersion in water under conditions — depth and duration — agreed between manufacturer and user, unlike the defined-jet tests of IP65/IP66. Always confirm the specific depth/time specification behind an IP68 claim.

IP68 or IP69 — which do I need?

IP68 targets immersion; IP69 targets high-temperature, high-pressure wash-down. Submerged equipment needs IP68; food-line equipment facing steam-jet cleaning needs IP69K-class performance. Our comparison guide covers the boundary cases.

Why do IP68 enclosures fail in service?

Almost always at cable entries and unsealed penetrations drilled on site. We machine and re-seal all cutouts in the factory and match glands to the actual cable schedule — site-drilling an IP68 box voids the immersion rating.

Can electronics be serviced inside an IP68 enclosure?

Yes — the lid seals are designed for repeated opening when correctly reassembled. We supply torque and gasket-lubrication instructions, and recommend spare gaskets for maintenance cycles.
