A span clamp and outdoor wire anchor are needed to drop telecommunication cable into a customer’s home. If a span clamp should come apart from a messenger wire or a self-supporting type of telecommunication cable, or if an outdoor wire anchor should come apart from the span clamp, the drop line will hang loose, which will create a facility fault. It is therefore necessary to prevent such accidents by ensuring that these components do not separate from the equipment. The separation of a span clamp or outdoor wire anchor can be caused by (1) loosening of the nut on the span clamp, (2) incorrect placement of the separation-prevention washer . (3) corrosion and subsequent deterioration of an iron fitting. (4) Conditions (1)and (2) can be prevented by properly installing the components, but deterioration caused by corrosion (3) cannot be prevented by proper installation work alone.Outdoor Wire Anchor is also called insulated / plastic drop wire clamp. It is a kind of drop cable clamps, which is widely used for securing drop wire on various house attachments. The prominent advantage of insulated drop wire clamp is that it can prevent electrical surges from reaching the customer premises. The working load on support wire is effectively reduced by the insulated drop wire clamp. It's characterized by good corrosion resistant performance, good insulating property and long-life service.
