XLPE Insulated Power Cable XLPE Insulated Power Cable

Product Description:

XLPE Insulated Power Cable is usually called as cross-linked cable, has the characteristics of high operating temperature , big transmission capacity, perfect electric performance, no limit for placing dropping variance and easy to be installed and maintenance convenience, which is directive product of the power cable develops.     The product is manufactured according to international electrician committee standard IEC60502-1997 and the National standards GB/T12706-2002, also defer to other national standards or the user requests to carry on the design and the production. and may produce being flame-resistant, fireproof, against mouse and the termite-proof, does not have uses and so on halogen low smoke environmental protection in the different situation serial products.

The product voltage level, amount of cores and section area 
voltage level:：0.6/1-26/35KV 
section：1.5-800mm2
cores：1-5

Note: the first category applies to the three-phase system in  which the fault in every grounding process lasts less than 1 min; the  second category to the three-phase system in which the fault in every  grounding process lasts generally less than 2 hours, with a maximum of 8  hours. 


2,Notes: ① as for models of  single-core cables in brackets used for AC system, the single-core  cables are shielded with non-magnetic materials.
       ② “ZR” before the models stands for flame-retardant products and “NH” for fire-resistant products.

3,The main technical indicators and the laying of the requirements
(1) DC resistant: every kilometer product core DC resistant should be no more than provision
(2) Voltage text: At ambient temperature, the cable conductor bring to bear 3.5Uo to ground , time 5min does not breakdown.
(3) Partial  discharge text: 3.6/6KV and above on the products between the conductor  and the metal shield voltage imposed 1.73 Uo, partial discharge does  not exceed the amount 5Pc.
Maximum conductor work temperature of  90℃,  250℃ short time is not more than 5 seconds, when the cable laying  the temperature should be less than 0℃. Cable minimum bend radius.
