What is multicast technology?

IP multicast (also known as multicast or multicast) technology is a TCP / IP that allows one or more hosts (multicast source) to send single packets to multiple hosts (once, at the same time) network technology. Multicast as one-to-many communication is one of the effective methods to save network bandwidth. In the application of network audio broadcasting, when the signal of one node needs to be transmitted to multiple nodes, whether it is repeated point-to-point communication or broadcast, it will seriously waste network bandwidth, and only multicast is the best choice. . Multicast enables one or more multicast sources to send data packets only to a specific multicast group, and only hosts that join the multicast group can receive the data packets. Currently, IP multicast technology is widely used in network audio / video broadcasting, AOD / VOD, network video conferencing, multimedia distance education, "push" technology (such as stock quotes, etc.) and virtual reality games.

Electrical Lockout equipment is used for locking out switched off circuit breakers, preventing re-energising, to control dissipation of residual energy, to ground electricity and also to effectively tagout equipment.

The plug completely sits inside the unit with the cable being fed through an access hole inside.Completely encloses electrical plugs to prevent accidental re-connection.

Our Electrical Plug Lockout devices accommodate a large variety of plug shapes and sizes and some require a key to prevent unauthorized plug connections.Device is made of rugged polypropylene and is for use with 110V,220V and 500V electrical plugs.

Surrounds the electrical plug and protects against accidental reconnection.Avoid electrical accidents by applying lockouts to prevent plugs from being inserted into a wall outlet. Use when plug will not remain under the exclusive control of the person performing service or maintenance.
