Summit Telecom is China leading manufacturer provides VX Terminal Stubbed Block 10~30 Pair, STUB Module, Connection Module, etc.
 

• Description:

1. Item Code: ST VX-TM
2. The VX Terminal Stubbed Block is developed for guaranteeing the simple, reliable and maintainable joint between the pairs of distribution cable and the chains of user installation or the ancillary circuits from the service equipment.
3. The construction of VX Terminal Stubbed Block ensures electrical protection and testing of lines, and because of the application to 5- polar insertable VX Terminal Stubbed Block is provided both the through connection and the number of other functions, as a result of which it is ensured the efficiency of the modernization of the allowed services without the resealing of the connections of wires.
4. For the use for such purposes, the VX Terminal Stubbed Blocks of the end fitting are arranged by the units of modules down 5 pairs, by maximum capacity to 50 pairs (with the step of a change in the capacity, equal to 5 pairs). The additional connection of official pair if necessary can be provided ford.
5. The construction of VX Terminal Stubbed Block is intensified because of the application of an angular tire through the stainless steel, which ensures mechanical strength to assembling. The elements of grounding each pair are electrically connected together, with the screen of cable and with the end fitting of grounding, located beyond the cable end of the Connection Module, near the connection of official pair, if the same is provided.
6. The pairs of cable are connected due to the plant conditions down the tail end of the block with the application of fitted contacts and with the subsequent hermetic sealing by filling for the sake of epoxy resin for guaranteeing the overall protection from the environmental effects. The openings under the fastening, which ensure the possibility of the STUB Module installation beyond the flat surfaces, are provided on both longitudinal sides of STUB Module.
7. VX Terminal Stubbed Block is especially recommended for:
a) Outdoor connections where the environmental conditions are extremely aggressive
b) Terminations where user development characteristics require future flexibility in terms of the type of protection or filtering capabilities.
8. Capacity of VX Terminal Stubbed Block: 10 Pair/11 Pair, 15 Pair/16 Pair, 20 Pair/21 Pair, 30 Pair/31 Pair.
