  • Why can cold-joints allow air to pass through

    Why can cold-joints allow air to pass through

    Insufficient vibration or consolidation during concrete placement can lead to voids or excessive air in interface between the two concrete sections (creating weakened bonding results and leading to cold joint formation). This is known as a concrete cold joint. The visible change between the two concrete surfaces could be a slight difference in color or texture. A cold joint is a visible or structural separation that occurs when fresh concrete is poured against previously placed concrete that has already begun to set. Instead of forming a monolithic (single, unified) structure, the two layers fail to bond properly. Cracking Cold joints often become points where cracks initiate and propagate. A residential project faced leakage issues in an underground water tank.

  • Huawei Industrial Switch STP

    Huawei Industrial Switch STP

    Huawei switches support the following spanning tree protocols: Spanning Tree Protocol (STP), Rapid Spanning Tree Protocol (RSTP), Multiple Spanning Tree Protocol (MSTP), and VLAN-Based Spanning Tree (VBST). STP is used on a LAN to prevent loops. Devices running STP discover loops on the network by exchanging information with each other, and block some ports to eliminate loops. STP refers to STP defined in IEEE 802. In another lesson, we will also learn Huawei RSTP Configuration. This chapter. Huawei CloudEngine S5735I-S-V2 series industrial switches (DIN rail-mounted) are next-generation industrial switches that provide flexible all-gigabit access and GE/10GE uplinks.

  • Must industrial distribution boxes be grounded

    Must industrial distribution boxes be grounded

    Each DISTRIBUTION BOX and controller must be grounded. 26 mm 2 (10 AWG) ground wire must be used, and in all other markets a 6 mm 2 must be used. Grounding of the units: Attach a ground wire from one of. A single grounding failure in your industrial facility can trigger catastrophic equipment damage, production shutdowns, or worse—fatal electrical accidents that were entirely preventable. Industrial electrical grounding requirements aren't just regulatory checkboxes—they're the foundation of. This guide covers everything you need to know about safe grounding in industrial plants, including key threats, terminologies, and grounding systems. Circuits are grounded to limit excessive voltage from lightning, transient surges, and unintentional contact with higher voltage lines, and to limit the voltage to ground during normal operation. 26 (Clearance. The recognition of a separately derived system is important when applying NEC requirements to system grounding, as discussed below. All the power sources mentioned above, except Static Power Converter, are magnetically operated devices with windings.
