请教各位，各厂家目前35kV交联电缆耐压试验按多高电压？65kV/5min还是65kV/30min或91kV/5min？

91kV/5min

飞刀 --- 2007-12-20 22:57:58

GB/T12706-2002标准有明确规定

PLWH --- 2007-12-21 10:55:47

标准我知道，91kV/5min或65kV/30min，我想知道多数厂家都是严格按GB/T 12706-2002做的吗？

ma800722 --- 2007-12-21 15:39:18

65kV/30min

wangsf1979 --- 2007-12-23 22:35:35

65KV/30min 或91KV/5min 都可以,看你试验设备承受的能力二都选一.

至少我们公司是严格按照国家标准做的.

我们厂一般就用91KV/5min 的

65kV/30min,我们是经常打的，91KV/5min 我们很少打了啊，

严格按GB/T 12706-2002 65kV/30min

SODDY6387 --- 2007-12-29 22:58:28

65kv/30Min是国家老标准，91kv/5Min是新标准。打91kv高压油杯的头很难作。

YZCYJ --- 2007-12-30 10:40:43

我们也是65kv/30Min,以前也用过91的,打坏了几个油杯!

按标准做，另外还要看你的设备能力

haimooo --- 2007-12-30 17:46:57

设备局限性，65kv/30min

65kV/5min ？你也太敢想了

65kv/30min 严格按国标执行

fyc8 --- 2008-01-02 21:46:25

建议楼主严格按国家标准去进行试验,如果不能按照标准进行例行试验,一旦电缆存在缺陷就不能及时发现了,到时真的是后患无穷呢.现在不少电缆企业由于采购的局放设备是老的设备,只能进行65/30min耐压试验.按91kv/5min进行耐压试验,对电缆头的做头要求比较高呢,另变压器油也要质量比较好的,否则头端容易发生击穿的.

nongheng --- 2008-01-04 13:48:04

我觉得这两个标准都差不多，要联系实际进行测试就行拉，

QC --- 2008-01-07 16:55:17
21

我们用65kv/30Min , 91kv/5Min对电缆本体有一定的伤害,并且终端处理不好,在外屏1cm左右容易击穿,和击穿油杯.

PLWH --- 2008-01-16 16:29:00
22

若接到大批量生产订单时，交货期很紧，采用65kV/30min方法试验，30min打一根绝缘线芯，从半成品到成品，一段3芯的交联电缆仅打耐压就需要3小时，从交货期角度考虑，似乎时间长了些。所以打65kV/30min不如打91kV/5min。

zhangluo --- 2008-01-27 13:13:23
23

91kv/5min快,适合产量大和设备允许的企业,

35kv头难做主要是局放问题,

电缆端头加均压环可明显改善试验质量

jydl --- 2008-01-28 14:32:43
24

一般情况下是91kv/5Min，主要聂决于你的局放设备是否能满足要求

hbszjly --- 2008-01-29 03:16:47
25

按GB T/16999 2005-35 应该是91KV/MIN

guying8 --- 2008-02-08 11:34:10
26

都是按照GB 12706做啊!到现在不知道有那个电缆厂自己弄!一个是耐压试验,一个是局部放电实验!!这个还不简单

shy --- 2008-02-13 21:01:58
27

1、35kV是指线电压，耐压试验电压我记得GB12706.2-2002标准要求是3.5*U0(U0指相电压），耐压试验电压值选择应首先搞清楚U0是多少。

2、5min耐压试验电压GB12706-2002标准我记得比GB12706-91标准提高了试验电压，老标准是2.5U0

3、耐压试验电压值应执行最新标准要求规定；如能确认延长时间至30min并相应降低试验电压值，试验结果是等效的，我认为也可以，毕竟耐压试验的目的是用来发现电缆绝缘中可能存在的严重缺陷(包括材料缺陷、工艺缺陷等问题）

65kv/30Min 好做，91kv/5Min有点难度，我们一般是做65kv/30Min ，91kv/5Min很少做，油杯很容易击穿

zhqpxt --- 2008-03-06 14:12:30

91KV/5min 可以使用硅胶高压成品端头试试!PASS

行业内可能更多采取65KV/30min标准做试验，91KV电压太高，对终端要求太高，极易把油杯打坏。

65kv，30分钟

王武 --- 2009-09-06 08:45:35

12706标准规定2.5U0----30min, 3.5U0----5min 两个任选

试验之前请确认是21/35KV还是26/35KV 前者 53KV/30min 或73，5KV/5min后者65KV/30min 或91KV/5min

叶儿 --- 2009-09-13 16:10:57

65KV/30min

除非购买方另有要求, 制造方可任选以下程序进行例行电压实验:

3.5U₀,5min;

2.5U_0,30min.

65KV/30min 或91KV/5min 都可以，GB/T 12706-2002有严格规定

但是大多数厂家都首选65KV/30min ，这种对电缆和试验设备都有好处，电压冲击小。

标准上有的

fyc8 --- 2017-06-23 09:34:26
56

不知大家想过这个问题没有？根据标准有二种，一是3.5U0 5分钟；二是2.5U0 30分钟，第一种打耐压难度较大；第二种耐压时间太长。如果将耐压值定为3U0，按照等效的原理，不知道耐压时间要多长？

fyc8 --- 2017-06-23 09:44:34
57

也不是我瞎想出来的，当初国标12706-2002修订的时候，只有一种规定：3.5U0 5min。后不少代表纷纷提出，国内的不少局放进口设备，当时的高压电压根本达不到91kV，如果就按此规定，进口的局放设备就要报废。后由上缆所国标起草人员蒋佩兰，提出了2.5U0，30min第二种方法，为了说明与第一种方法等效，用了半天的时间向与会人员用理论公式来证明的。不过大部分人员听不懂的，用的理论公式有点高深的。我当时也未听的懂。呵呵！

65kV/30min，同上，。91kv 的设备和油杯都是你不稳定因素

出厂是91kv/5Min
